00:04.55 | fsmithred | I haven't used OSS since 2000 |
00:05.36 | bozonius | it appears interest in OSS, even OSS4, is rather waning, from what I've read about it these few minutes since blurting the question |
00:06.36 | bozonius | seems that the original open source was taken private, which (as usual) miffed a lot of folks, then the company that took it private opened it up again... <sigh> |
00:07.11 | bozonius | maybe that whole episode left a bad taste for many and that's why it no longer seems to have much street value |
00:07.51 | bozonius | well, anyway, as promised, I am reading the alsa pages to try to get a deeper understanding of sound using ALSA. |
00:08.27 | fsmithred | afk for a bit |
00:10.45 | gnarface | bozonius: alsa has been worth it. i don't know much about OSS4 other than that support for it is rare |

00:34.28 | bozonius | http://alsa.opensrc.org/Dmix NOTE: For ALSA 1.0.9rc2 and higher you don't need to setup dmix for analogue output. Dmix is enabled by default for soundcards which don't support hardware mixing. You still need to set it up for digital outputs. |
00:34.40 | bozonius | we are running 1.0.27 or so |
00:40.10 | gnarface | bozonius: yea it's been on by default in the default pcm for years now, which is called literally, "default" |
00:40.41 | gnarface | bozonius: but you can't trust all your programs will use "default" by default, many of them do really boneheaded stuff and default to "hw:0,0" or something equally disruptive |
00:41.28 | gnarface | bozonius: most of the good ones have built-in controls to at least select that much, however some don't have anything and require some alsa config trickery (~/.asoundrc customizations are the common way to address this on a per-user basis) |
00:41.56 | bozonius | but popular programs like firefox or chromium... |
00:42.08 | bozonius | one would think that they would get it right |
00:42.20 | gnarface | one would, if one was childishly naive |
00:42.27 | bozonius | there'd be a furor otherwise |

00:44.28 | gnarface | sorry, i get where you're coming from, and i know that this is gonna be hard for you to wrap your head around |
00:44.32 | gnarface | but the world is a hugely unfair place |
00:44.40 | bozonius | no fucking kidding |
00:44.47 | gnarface | and largely, most of the people in it are slow on the uptake |

00:48.50 | bozonius | how are we supposed to get this information so we can actually FUCKING understand these technical nuances? |
00:49.11 | gnarface | bozonius: so, when it comes to funded software that moves MILLIONS of dollars, the first rule is to stop assuming anything but the money is the goal. if you can get past that prejudice, everything about what Mozilla is doing now makes sense. |
00:49.58 | bozonius | keeping millions confused and frustrated hardly seems like a useful means of making money |

01:12.52 | gnarface | (this will test dmix unless you've altered your alsa config to sabotage stock default behavior somehow) |
01:13.20 | gnarface | it will test dmix and full duplex recording at the same time actually |
01:13.42 | gnarface | if that doesn't work right, nothing else is gonna |
01:14.54 | gnarface | you're absolutely right that it's dumb for firefox not to just have a field in about:config for changing the default audio backend from pulse to whatever |

07:21.23 | gnarface | bozonius: even on the host, without pulseaudio? |
07:21.55 | bozonius | this was on Devuan guest VM, w/o PA |
07:21.56 | gnarface | bozonius: and nothing else accessing the soundcard at that time, and the capture volume for the mic selected and unmuted in alsamixer, with the volume up (on the *capture* tab not the playback tab) |
07:22.27 | gnarface | should work, barring a driver bug that suggests an alsa.conf problem |
07:26.37 | bozonius | hold on; my bad |
07:26.46 | bozonius | I had FF running, so that was an invalid test |
07:26.55 | gnarface | but if it's in a guest, i *think* it can *also* be a alsa.conf problem on the host *or* in the VM itself |
07:26.57 | bozonius | I killed ff (still Devuan VM now) |
07:27.21 | bozonius | sorry, I just wasted your time b/c I didn't do the test correctly |
07:27.33 | muep | also could be something specific to what mechanism is used to get sound out from the VM |
07:27.54 | bozonius | I just ran it again and no errors. I hear "front left, front right" repeatedly (but nothing else) I did not speak during the test |
07:27.56 | muep | at least qemu/kvm has many options and I'd guess virtualbox has some of its own |
07:28.31 | gnarface | bozonius: were you still getting overrun errors? |
07:28.38 | bozonius | no, no errors |
07:28.53 | bozonius | sound was clear, undistorted |
07:28.54 | gnarface | bozonius: did you check the capture tab in alsamixer? you might not have the mic selected |
07:29.25 | muep | what kind of VM is this? |
07:29.30 | gnarface | bozonius: when i run that here, even if i don't speak, i can clearly hear the ambient noise of the room coming through over the speaker-test |
07:29.49 | bozonius | let me do this again, speaking while it runs... |
07:30.15 | gnarface | bozonius: you can run the speaker-test in a separate terminal from the arecord|aplay commands if you want |
07:30.27 | bozonius | ok I can hear myself echoed through speakers and the speaker-test output also |
07:30.37 | gnarface | ok |
07:30.39 | gnarface | so that works |
07:30.46 | gnarface | but firefox jams it |
07:30.47 | bozonius | (sorry for my bumbling) |
07:30.50 | bozonius | right |
07:31.03 | gnarface | no worries, i had trouble with this part at first too |
07:31.11 | gnarface | this is the part pulseaudio (badly) hides from the user |
07:31.34 | gnarface | it's because it's stripped down more or less to very little other than the basic hardware features |
07:31.57 | bozonius | JACK supposedly does a better job, but it is still a "layer" on top of ALSA, and can still have at least some latency |
07:32.07 | gnarface | yes, you might often hear stuttering in pulseaudio while doing this |
07:33.56 | *** join/#devuan thaller (~thaller@109.196.217.23) |
07:34.02 | gnarface | so, probably, if firefox does this in ANY VM, it will do it to ALL of them AND the host at once |
07:34.14 | gnarface | because they're sharing one soundcard |
07:34.19 | gnarface | it's a physical limitation |
07:34.34 | gnarface | (you could use multiple soundcards though but most people just upgrade to one that does hardware mixing) |
07:35.22 | muep | I do not think the VM has normally access to the soundcard |
07:35.33 | bozonius | My soundcard is onboard. And it's about 3-4 years old, though the model may be older |
07:35.55 | bozonius | ASUS M5A78L/USB3 |
07:36.04 | gnarface | muep: well it has to if you're gonna play sound |
07:36.17 | bozonius | no, I can always add a separate card |
07:36.17 | gnarface | muep: i didn't say whether i thought it was a good idea or not |
07:36.34 | muep | usually the VM hypervisor provides an emulated soundcard that is implemented purely in software. then the guest os writes audio samples to a buffer in that emulated sound card and the emulated audio card implementation copies samples from there to actual sound card |
07:36.39 | bozonius | I am pretty sure there is a soundcard around here... |
07:37.03 | gnarface | bozonius: well, now that you understand how the conflict occurs, you in theory could avoid it too |
07:37.19 | gnarface | though with newer firefoxes you'll need pulseaudio or apulse |
07:37.23 | bozonius | muep: In the interests of efficiency and removing latency, the vbox devs may have taken a different approach |
07:37.24 | gnarface | i don't know any way to avoid that problem yet |

07:40.03 | bozonius | wonders who the heck is Zelda? |
07:40.18 | muep | if I was using audio a lot from a VM I might actually enable the TCP transport in my VM host and set up pulseaudio-compatible applications inside the VM to connect directly to the host |

12:27.45 | utente | question: is correct i got so poor write speed of 15MB? i wist 40, at least 30MB/s. i can accept a degradate speed because of software raid, but 15MB/s is too much low. |

12:32.33 | gnarface | i dunno |
12:32.37 | utente | mmm |
12:32.39 | gnarface | it would at least delay it that's for sure... |
12:32.45 | gnarface | check iotop |
12:32.48 | utente | i use ext4 as fs, maybe it could impact? |
12:32.54 | gnarface | eh, probably not |
12:33.12 | gnarface | but try different block sizes maybe |
12:33.20 | utente | i have not iotop instlled, but id yes, what i have to loop for into iotop? |
12:33.37 | utente | what block sizd do you suggest_? |
12:33.55 | utente | i have not iotop installed, but if yes, what i have to look for into iotop? |
12:34.12 | gnarface | 512 and 4K |
12:34.31 | gnarface | also you can benchmark with hdparm and bonnie++ |
12:34.58 | gnarface | if you're not using the "performance" cpu governor it could effect things |
12:35.04 | gnarface | just make it slower |
12:35.05 | utente | hell. i must move the PC near intenet cable and instal all the utilities. |

12:35.19 | gnarface | that's a problem |

12:35.32 | utente | logistical problem, yes, |
12:35.50 | utente | i am doing irc in one room, pc is into another room. |
12:36.35 | gnarface | well in theory you could install locally and copy the deb files to a usb disk from the package cache too |
12:37.07 | gnarface | but if the installed packages are very different between the local system and the other one that may not be as easy |
12:37.53 | utente | i use devuan 1.0 stable, i suppose packages did not changed so fast. |
12:39.13 | gnarface | should be in /var/cache/apt somewhere |
12:39.23 | utente | anyway: even if i use a test tool what it can tell me? all in all, i did time dd if=/.... so i know the spped reached during write and read operation. what cai i got more form iotop /bonnie++ etc? |
12:39.24 | gnarface | try: find /var/cache/apt -iname '*.deb' |
12:39.40 | gnarface | (as long as it hasn't been cleaned since you installed) |
12:40.12 | gnarface | iotop is like top for io |
12:40.17 | gnarface | for your harddrive usage |
12:40.21 | utente | nope, i always do apr-get clean. but those packages are not into archive, cos they are not on fist cd of devuan, the only one i used. |
12:40.34 | gnarface | ah, i see |
12:40.54 | gnarface | i'm not sure which cd they are on, i mostly netinstall |
12:41.00 | utente | i know iotop, i used in past and i know what it is the usage. but i cannot se what more information it can give me |
12:41.12 | gnarface | oh maybe something else using it |
12:41.51 | utente | let me go there to see if hdparm is avaiable. maibe it is not activated the dma. |
12:44.30 | gnarface | also you asked if ext4 might be the problem, so i suggested bonnie++ to do some checks of that |
12:45.07 | gnarface | when you format with ext4 you can set block size at format time |
12:45.29 | gnarface | you should check the specs on those drives to make sure the block sizes match if they're 1k or 4k |
12:45.35 | gnarface | (not possible if it's 512 i think) |
12:45.46 | gnarface | all this will help at little, at least |
12:46.06 | gnarface | maybe there is something weird with those drives where they're really bad at the block size you used when you formatted them |
12:46.09 | gnarface | i'd believe that is possible |
12:46.50 | gnarface | they ARE green drives after all |
12:46.58 | gnarface | which means they're also only 5200RPM |
12:47.10 | gnarface | 5400 i mean? |
12:47.33 | gnarface | 5400 |

13:49.07 | gnarface | i don' |
13:49.11 | gnarface | i don't know |
13:49.36 | gnarface | what does iotop say when you're not running dd? does io go to almost 0? or is there still something using up 12% of it at all times? |

13:54.34 | gnarface | utente: https://www.thomas-krenn.com/en/wiki/Ext4_Filesystem#Lazy_Initialization |
13:54.43 | gnarface | i bet that's where that 12% is going, at least |
13:54.46 | gnarface | so it's still formatting |
13:55.07 | gnarface | because ext4 actually formats REAAALY slow in real life |
13:55.14 | gnarface | so that's probably your bottleneck too |
13:55.27 | utente | wtf! |
13:55.39 | utente | could be. really could be. |
13:55.51 | gnarface | yea, now imagine that overhead doubled while it gets copied to the second disk |
13:55.58 | utente | i guess to move or not to other fs |
13:56.17 | gnarface | eh, it'll eventually be done |
13:56.24 | utente | there is a way to see how much wait thil formatting finish? |
13:56.35 | gnarface | probably but i have no idea |
13:57.07 | gnarface | a 1TB disk might take a good several hours |
13:57.15 | gnarface | it also might have to start over from scratch if you stop it |
13:57.35 | gnarface | it wouldn't be unexpected for it to take a day or two |
13:57.36 | utente | so ath this point the only way is to wait untill ext4lazy disappear |
13:57.45 | gnarface | yea maybe |
13:57.51 | gnarface | maybe just dont worry about it for a couple days |
13:57.58 | utente | got it. |
13:58.27 | gnarface | next time, if you remember to, you can probably choose to format them up front |

16:03.28 | fsmithred | after you leave the options window, no. but you can stop the installer and start over. |
16:03.53 | fsmithred | whole install only takes about 10 minutes |
16:05.06 | romo | utente: thanks, doesn't sound familiar though. maybe reinstall might be quicker in that case... |
16:05.21 | romo | fsmithred: install is already done, but encountered some 'problems' |
16:05.22 | fsmithred | romo, where are you in the install? |
16:05.33 | romo | will the uuid option work with encrypted root? |
16:05.35 | fsmithred | what problems? |
16:05.51 | fsmithred | if it won't, it'll tell you |
16:06.00 | fsmithred | there's something around there that won't work |
16:06.13 | fsmithred | maybe labels. I forget, but hang on and I'll check. |
16:06.22 | romo | yeah... alright, here's the extended problem: |
16:07.23 | fsmithred | UUIDs in fstab won't work with encrypted filesystems and |
16:07.24 | fsmithred | <PROTECTED> |
16:07.32 | romo | set up encrypted root, separate boot, no uuid (cause I think it was complaining). disconnected all drives except system to not mess things up |
16:07.47 | fsmithred | good so far |
16:07.56 | romo | now the system will only boot/unlock if there are absolutely no other drives connected... |
16:08.09 | fsmithred | ok |
16:08.38 | fsmithred | there should be uuids in grub.cfg |
16:08.46 | romo | I have full access to the encrypted root if I boot from live medium, unlock and mount, no problem |
16:08.58 | fsmithred | ok |
16:10.38 | romo | could you expand on that, I'm super noobish regarding grub... or what to do now. |
16:10.56 | fsmithred | hang on, I'm checking my own setup to see how it's done |
16:11.06 | fsmithred | I'm using labels in fstab, not uuid |
16:11.12 | fsmithred | but I know grub uses uuid |
16:11.50 | fsmithred | and it can be confusing because the physical volume gets a uuid and the filesystems inside it get their own |
16:12.41 | fsmithred | did it boot correctly with only the one hard drive? |
16:13.09 | romo | I'll second that confusing part. So if I reinstall, disable UUID and enable Lables instead I should be fine? |
16:13.45 | fsmithred | no, sorry. labels won't work with encryption, either. |
16:14.11 | romo | it tried to unlock the corect volume but failed at it as if you enter the pw incorrectly. error message reads: 'Cryptsetup: unknown fstype, bad password or options?' |

16:18.00 | fsmithred | which is what I have to do |
16:19.05 | romo | just thought: should this not be fine if I reinstall after connecting the system drive to sata1, since it will no longer switch position upon connecting other stuff |

16:22.37 | msiism | fsmithred: ok, thanks |
16:22.43 | fsmithred | if the drive is not in the first port, then yeah, the system no longer sees it as first because you plugged stuff in front of it |
16:22.58 | fsmithred | easy test: get the boot device menu and select |
16:23.16 | fsmithred | some key should get you there at post screen |
16:23.31 | fsmithred | F12, F8, ESC, it should tell you |
16:24.03 | fsmithred | although it still might have problems |
16:24.42 | romo | yes. now that you mention it: I can be certain I hit the right drive. Cause the bootloader loocks differently for the others. |
16:25.17 | fsmithred | but it might think it's supposed to be /dev/sda but it's now something else |
16:25.37 | fsmithred | reboot and press c at grub boot menu |
16:25.53 | fsmithred | can you tell the drives apart by what partitions they have? |
16:27.08 | romo | well, there's some similar. in the mainboard boot menu they have sort of 'extensions'. does it display partition size? with sizes I can tell them apart. |

16:29.16 | romo | is it very complicated? I have a shortage of machines atm and I'm on the one in question... |
16:29.35 | fsmithred | it's a few commands |
16:29.45 | fsmithred | but easier if we could still talk |
16:29.56 | fsmithred | you would type the following at the prompt: |
16:30.01 | fsmithred | set root=(hd |
16:30.13 | fsmithred | and then press TAB (maybe twice) |
16:30.22 | *** join/#devuan metax (~metax@gateway/tor-sasl/metax) |
16:30.23 | fsmithred | and it would tell you what hard drives you have |
16:30.40 | fsmithred | first is hd0, second is hd1, third hd2 |
16:31.18 | fsmithred | then to complete that line, you'd give it the partition (the one for /boot) |
16:31.35 | fsmithred | where's it plugged in? third sata slot? |
16:32.07 | romo | have to look that up in the board menu again, but something like that, yes. |
16:32.53 | fsmithred | anyway, when you figure out which one is the right hard drive, add the number and press TAB again (maybe twice) so you'd have something like this on the command line |
16:33.03 | fsmithred | set root=(hd2, |
16:33.12 | fsmithred | and TAB will show you the partitions |
16:33.29 | fsmithred | if first partition was used for /boot, then |

16:34.55 | fsmithred | then |
16:35.03 | fsmithred | initrd /initrd.img |
16:35.27 | fsmithred | and you can use TAB completion on any of these to make sure it really exists |
16:35.29 | fsmithred | then |

16:35.41 | metax | can i update my devuan jessie to stretch? |
16:36.05 | fsmithred | I think you'd need to change it to debian jessie first |
16:36.19 | fsmithred | or do you want devuan ascii? |

17:35.49 | fsmithred | put a comma after the hd0 and hit TAB again, and it should show you the partitions |
17:36.00 | fsmithred | msdos_1, msdos_2, and so on |

17:45.57 | fsmithred | no underscore like I had it before |
17:46.05 | fsmithred | you do have /boot on the first partition? |
17:46.50 | romo | I tried booting into live media, using the lsblk information, tried to count according to the board "mapping" starting with hdd0... and tried to input just everything with "sdX2" in it. |
17:47.34 | fsmithred | then on the linux line, use root=/dev/mapper/sda2_crypt |

18:23.32 | romo | fsmithred: Sadly no, how about you? |
18:23.37 | fsmithred | yes |
18:23.43 | fsmithred | one thing I told you wrong |
18:23.59 | fsmithred | on the linux line, /vmlinz will be /vmlinuz-<version> |
18:24.08 | fsmithred | use tab completion |
18:24.11 | fsmithred | same for the initrd |
18:24.49 | fsmithred | maybe it worked for me because I have a label on the filesystem. I used root=/dev/mapper/root_fs |
18:25.36 | fsmithred | oh, get the uuid for the root filesystem (I think you'll have to boot from CD or USB and open it first) |
18:26.08 | fsmithred | then on the linux line, you should be able to use root=uuid and type the first few numbers/letters then tab-complete it |
18:26.36 | fsmithred | where did it fail? any error message? |
18:27.33 | romo | still had no way to determine partition letter. grub doesnt offer uuid for encrypted, like you assumed and trying did not work |
18:28.11 | fsmithred | you shouldn't need the partition letter |
18:28.14 | fsmithred | oh |
18:28.16 | fsmithred | yes you should |
18:28.17 | fsmithred | shit |
18:29.08 | fsmithred | what's in the fstab? |

18:29.26 | *** join/#devuan jathan (~jathan@206.167.44.205) |
18:29.51 | romo | I'd like to second the 'shit' part. don't know about fstab. so I boot into live, unlock and then cat fstab about uuid? |
18:30.11 | fsmithred | cat fstab for whatever it says for the root partition |
18:30.17 | fsmithred | or anything else interesting |
18:30.50 | fsmithred | you could then assign a label |
18:30.53 | fsmithred | but... |
18:31.00 | fsmithred | I just thought of something easier |
18:31.52 | fsmithred | that might be debatable, but you could chroot the installation and run grub-install and update-grub |
18:31.55 | romo | I was about to go encrypted lvm and torch the entire drive in the process. now I'm interested |
18:31.58 | fsmithred | and let grub figure it out |
18:32.27 | fsmithred | we should probably go to pm if you want to do that |
18:32.44 | fsmithred | assuming you can get here from the live session |
18:35.10 | romo | not sure, 2nd rig has some issues regarding getting it online. I will have to be able to recreate this on different machines. that's why I'm thinking: |
18:35.25 | romo | is dvd or netinst-img with encrypted lvm viable atm? |
18:35.39 | fsmithred | if you have a regular installer iso, you can do lvm |
18:35.47 | fsmithred | any of them. netinstall or dvd |
18:37.18 | romo | I tested dvd-img at some point and it did not seem to retrieve updates after the install (?) which left me super concerned. but if they are both ok in general terms... |
18:37.41 | fsmithred | if you installed with a network mirror there were no updates to be had. |
18:37.50 | fsmithred | you already had them |
18:37.51 | romo | I mean I "lose" the drive, a lot of control and rescue potetial, but I could do this on my own repeatedly without effort |
18:38.48 | fsmithred | what are you losing? |
18:40.02 | romo | the thing I liked the most about the desktop life that I could just allocate a super tiny ammount of space to the system install. If I remember correctly encrypted lvm will take up the entire drive (and wipe it for hours) |
18:40.21 | romo | *live, English, so difficult at times. |
18:40.22 | fsmithred | you can skip the wipe |
18:40.47 | fsmithred | and you can make the lvm container any size you want with manual partitioning (a labyrinth) |
18:41.14 | fsmithred | another approach would be to do the install with all the drives connected |
18:41.25 | fsmithred | but you better know which one is which |
18:42.40 | fsmithred | I've done it with three or four drives attached. The live installer will only mess with the drive(s) you tell it to use. |
18:44.20 | romo | yeah, I made a spreadsheet with pros and cons. thing is: next time a drive whistles in an unexpected manner I would want to swap stuff around to read smart data etc. pp. without caring. |
18:45.05 | romo | guess I'm heading for netinst, which is the only one I have not tried so far. |
18:45.33 | fsmithred | or get all the uuids during a live session and plug them into /etc/fstab and /etc/crypttab |
18:46.34 | fsmithred | why do you need to swap anything to read smart data? Just open a root terminal and read it from the drive. |
18:49.13 | romo | those would be external ones from other machines, docking station... |

19:15.15 | fsmithred | ok, find a tutorial on doing encrypted lvm at forums.debian.net or maybe at the debian wiki |

20:58.16 | golinux | rsyslog stuff |
20:58.37 | fsmithred | either from backports or an alternate: syslog-ng or busybox-syslogd |
20:59.13 | fsmithred | if you are a fanatic like some of us and exclude libsystemd0, you will be disappointed - xorg needs it |
20:59.41 | DeFender1031 | I'm not sure what rsyslog is, but if it's really as simple as including something from backports, couldn't it be done on the repo end? |
21:00.18 | fsmithred | stuff happens slowly around here |
21:00.49 | fsmithred | it's actually a slightly newer version in ascii than in backports, so it needs to be recompiled. |
21:00.56 | ca-on-adam | If XOrg depends on something connected to systemd, does that mean that XOrg will have to be forked into a non-systemd variant? |
21:01.46 | fsmithred | the default desktop install, from installer iso or from live iso already includes libsystemd0 |
21:01.56 | fsmithred | the core devs are not so concerned with that |
