| 00:00.32 | KotCzarny | i meant, can i get that node working without oss emulation module |
| 00:03.31 | KotCzarny | ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM pcm.!default |
| 00:03.36 | KotCzarny | fun. |
| 00:04.39 | DocScrutinizer05 | the ! is illegal char I'd guess |
| 00:04.52 | DocScrutinizer05 | it's a special meaning char not part of name |
| 00:05.28 | KotCzarny | umkay, something is working |
| 00:05.41 | KotCzarny | i even get some feedback when tapping on the mic |
| 00:05.50 | DocScrutinizer05 | honestly, an empty device string is same like "default" |
| 00:05.56 | DocScrutinizer05 | afaik |
| 00:07.34 | DocScrutinizer05 | afk, cya |
| 00:07.39 | KotCzarny | thx, and gn |
| 00:10.37 | KotCzarny | fun. device is still opened after program closed (and i did close both streams) |
| 00:14.41 | DocScrutinizer05 | you need to free them too iirc |
| 00:14.59 | DocScrutinizer05 | just closing isn't enough |
| 00:15.15 | KotCzarny | sure, but now that app closed, how do i free them? |
| 00:15.23 | DocScrutinizer05 | or rather, closing might actually fail when you didn't free them beforehand |
| 00:15.44 | DocScrutinizer05 | good question, prolly reload the als kernel module |
| 00:15.47 | DocScrutinizer05 | dunno |
| 00:15.49 | KotCzarny | hehe |
| 00:15.59 | KotCzarny | reboot then |
| 00:16.24 | DocScrutinizer05 | what makes you think they are still open? |
| 00:16.57 | KotCzarny | [ 3808.617187] EAC mode: play enabled, rec enabled |
| 00:17.09 | KotCzarny | and no 'disabled' line in dmesg later on |
| 00:17.16 | KotCzarny | also, can't run app second time |
| 00:17.22 | DocScrutinizer05 | hmm |
| 00:18.22 | DocScrutinizer05 | no idea. actually that type alsa_dsp is new to me |
| 00:18.39 | KotCzarny | told you, it's hairy |
| 00:18.59 | DocScrutinizer05 | must be the kernel interface to ... dsp ;-) |
| 00:19.02 | KotCzarny | pity they couldn't write proper kernel device |
| 00:19.27 | KotCzarny | that would keep to standards and failsafe from user hackings |
| 00:20.27 | KotCzarny | yeah, it fails at snd_pcm_open |
| 00:20.36 | KotCzarny | so i can't even reset it without the reboot |
| 00:21.06 | DocScrutinizer05 | OpenMAX IL |
| 00:21.20 | KotCzarny | yeah, 'open' 'max' |
| 00:21.26 | KotCzarny | both lies |
| 00:21.31 | DocScrutinizer05 | http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Architecture/Multimedia_Domain |
| 00:21.40 | DocScrutinizer05 | it's prolly a TI thing |
| 00:21.52 | DocScrutinizer05 | DSP-bridge |
| 00:22.07 | KotCzarny | but you are reading n900's docs |
| 00:22.42 | DocScrutinizer05 | yes, but the OMAP2 isn't that much different in that regard |
| 00:22.54 | KotCzarny | it is, driver is worse |
| 00:22.55 | DocScrutinizer05 | afaik it also has a DSP |
| 00:24.05 | DocScrutinizer05 | and I guess alsa_dsp is ALSA's interface to OpenMAX IL or whatever the thing is called on OMAP2 |
| 00:24.40 | KotCzarny | ok, so how do i close the bastard properly? |
| 00:24.45 | KotCzarny | snd_pcm_drop ? |
| 00:24.52 | KotCzarny | then snd_pcm_close? |
| 00:25.06 | DocScrutinizer05 | unload the kernel module omap-dsp or whatever it's called |
| 00:25.09 | KotCzarny | nope |
| 00:25.11 | KotCzarny | builtin |
| 00:25.15 | DocScrutinizer05 | aah |
| 00:25.30 | DocScrutinizer05 | check source for aplay |
| 00:25.41 | DocScrutinizer05 | it's the reference inplementation |
| 00:28.46 | KotCzarny | i think it just uses snd_pcm_close |
| 00:29.03 | KotCzarny | unless there is something to error handling |
| 00:30.36 | DocScrutinizer05 | as mentioned you need to free stuff before close will succeed |
| 00:31.06 | KotCzarny | ok, got disabled msg |
| 00:31.53 | KotCzarny | oh, fun, it stays opened when closing app via ctrl-c |

| 00:36.37 | KotCzarny | nah, it's just that author of the app didnt add snd stop func at all close cases |
| 00:38.01 | DocScrutinizer05 | sorry, can't help any further. That's the end of my alsa 'expertise' |
| 00:38.15 | KotCzarny | no worries, it almost works |
| 00:38.30 | KotCzarny | still have to hack at buffers (clicking etc) |
| 00:38.58 | DocScrutinizer05 | twinkle-1.1/src/audio/audio_device.cpp is about as much as I know about ALSA |
| 00:39.04 | DocScrutinizer05 | nice code |
| 00:39.30 | DocScrutinizer05 | I found the // Without the snd_pcm_hw_free, snd_pcm_close sometimes fails. |
| 00:40.05 | KotCzarny | i free hw just after init |
| 00:40.09 | DocScrutinizer05 | since nobody but me bothers to check error return code of a close() |
| 00:40.14 | KotCzarny | or not |
| 00:40.31 | *** join/#maemo dreamer (~henk@melange.soleus.nu) |
| 00:42.43 | DocScrutinizer05 | and yes, ALSA docs suck in that they don't exlain when and how to use snd_pcm_hw_free() and *close() etc |
| 00:47.40 | DocScrutinizer05 | get twinkle-1.*/src/audio/audio_device.cpp it's probably pretty instructive particularly when you like OSS |
| 00:48.00 | KotCzarny | i'm tired a bit |
| 00:48.08 | KotCzarny | so for now i just install signal handler |
| 00:49.16 | DocScrutinizer05 | http://privatepaste.com/ece01709c6 |
| 00:49.47 | KotCzarny | i wouldnt call it simple interface |
| 00:50.13 | KotCzarny | but in my case it was the missing signal handler |
| 00:50.28 | KotCzarny | i'm amazed that kernel doesnt close the device on it's own... |
| 00:50.56 | KotCzarny | i guess that's the reason of n8x0's audio being flaky (sometimes works, sometimes not) |
| 00:53.08 | KotCzarny | can i catch -KILL ? |
| 01:10.24 | ZetaR | KotCzarny: SIGKILL cannot be caught. |
| 01:10.42 | KotCzarny | yeah. pity |
| 01:11.44 | ZetaR | Well, it does give you a way to kill a program that is hanging and refusing to respond to other signals. |
| 01:12.28 | KotCzarny | yeah, still, if i will ever have to kill this app via -KILL, audio device will be blocked |
| 01:14.07 | ZetaR | That... sounds like really poor design. |
| 01:14.19 | KotCzarny | on the nokia/ti, yes |
| 01:14.42 | ZetaR | You should immediately free resources when the blocking program gets killed. |
| 01:17.35 | *** join/#maemo Humpelstilzchen (erik@f054027165.adsl.alicedsl.de) |
| 01:18.59 | ZetaR | Unfortunately, I don't really know much about OMAP and ALSA, so I can't really help you out. |
| 01:19.30 | KotCzarny | nah, as i've said, it was a missing signal handler, it's fixed now (to a point) |
| 01:19.49 | KotCzarny | do you know c? |
| 01:20.34 | ZetaR | Yeah, but not real experienced. |
| 01:20.43 | KotCzarny | <PROTECTED> |
| 01:20.46 | KotCzarny | what does it do? |
| 01:22.20 | ZetaR | Hm, let me check K&R. Not sure what the >> is for. |
| 01:22.30 | KotCzarny | >> is bit shift |
| 01:22.36 | KotCzarny | but is >>= special? |
| 01:23.03 | ZetaR | Oh, well that sounds like you have an array and you are bit shifting and assigning a 1. |
| 01:23.16 | KotCzarny | o.o |
| 01:23.29 | KotCzarny | i wonder what the author meant by it.. |
| 01:23.38 | KotCzarny | but for shift you need param |
| 01:23.46 | KotCzarny | as in var>>2 etc |
| 01:25.43 | ZetaR | Hmm, maybe it is some other thing then. |
| 01:30.26 | ZetaR | According to K&R, most of the binary operators have a corresponding assignment operator, which is what >>= is. So that line should be equivalent to "process_buffer[i] = process_buffer[i] >> 1;" |
| 01:30.42 | KotCzarny | uhum |
| 01:31.03 | ZetaR | "expr1 op = expr2" is equivalent to "expr1 = (expr1) op (expr2)" |
| 01:31.41 | KotCzarny | i still don't know what app author wanted to achieve, because it only shifts by 1 bit then overwrites it next |
| 01:32.59 | ZetaR | Unfortunately, K&R does not contain the necessary rituals for divining the intentions of other programmers. |
| 01:33.35 | KotCzarny | http://pastebin.com/raw.php?i=miq1Ty4j |
| 01:33.39 | KotCzarny | this is the part of the code |
| 01:33.44 | KotCzarny | ignore <---> |
| 01:34.02 | KotCzarny | process_buffer is audio data, 2ch, 16bit samples |
| 01:34.37 | ZetaR | That doesn't overwrite it. |
| 01:34.39 | KotCzarny | if i read it correctly, it overwrites one channel with the other shifted by one bit |
| 01:35.17 | ZetaR | Oh, I thought you meant it overwrites it uselessly. |
| 01:36.20 | KotCzarny | process_buffer data type is short |
| 01:37.15 | ZetaR | So it shifts the samples in the array by one, and bitshifts the samples by one? |
| 01:37.32 | KotCzarny | it's late, i might be wrong/blind |
| 01:37.38 | ZetaR | Sorry, I need to go AFK for ~30min. |

| 02:01.09 | DocScrutinizer05 | hey, that divides by two (>>1) and copies left into right chan |
| 02:01.40 | KotCzarny | yeah, that's why i don't understand it |
| 02:02.04 | DocScrutinizer05 | which makes sense since stereo->mono later on adds both channels and thus compensates for the divide by 2 aka rightshift |
| 02:02.19 | KotCzarny | huh? |
| 02:02.50 | KotCzarny | so it's primitive stereo->mono code? |
| 02:02.53 | DocScrutinizer05 | it's prolly mono isgnal in left chan of a stereo stream |
| 02:03.40 | DocScrutinizer05 | this code copies left chan into right chan so it's balanced stereo, and compensates for the volume increase that causes |
| 02:04.03 | KotCzarny | what do you mean by 'balanced stereo' |
| 02:04.06 | DocScrutinizer05 | it's rather mono->stereo |
| 02:05.35 | DocScrutinizer05 | input is L?L?L?, output is (L/2)(L/2)(L/2)(L/2)(L/2)(L/2) |
| 02:05.50 | DocScrutinizer05 | ? is probably 0 |
| 02:05.58 | DocScrutinizer05 | or bogus data |
| 02:06.19 | KotCzarny | i could understand that it overwrites right chan with quited left chan |
| 02:06.29 | DocScrutinizer05 | a correct stereo input would be LRLRLR |
| 02:07.22 | DocScrutinizer05 | looks like what I'd do to a headset mic input |
| 02:07.46 | KotCzarny | unless your mic input is really stereo |
| 02:07.47 | DocScrutinizer05 | which per definition is on left channel when input is stereo |
| 02:07.57 | KotCzarny | or if input is line-in |
| 02:08.08 | DocScrutinizer05 | never seen a headset with stereo mic :-) |
| 02:08.34 | KotCzarny | this app comes from desktop |
| 02:08.50 | KotCzarny | but ok, thanks for helping me understand the author |
| 02:09.21 | DocScrutinizer05 | it copies left into right channel and attenuates both by 50% |
| 02:09.26 | KotCzarny | yeah |
| 02:09.42 | KotCzarny | now i have to tidy up the block sizes he uses |
| 02:14.01 | ZetaR | It seems that DocScrutinizer05 knows the correct divining rituals we were missing. :) |
| 02:14.20 | KotCzarny | or just had his powernap |
| 02:14.21 | KotCzarny | ;) |

| 02:18.07 | KotCzarny | MUAHAHAHAHA |

| 19:06.13 | freemangordon | I'd bet on that |
| 19:06.19 | KotCzarny | vectis, btw. is there /dev/dsp file? (ignore /dev/dsptask*) |
| 19:07.48 | freemangordon | bencoh: seem nemomobile iphbd has some differences compared to maemo, but I wonder if I should arm IDA and RE it, should be pretty much easy task with all those headers and source code around |
| 19:08.49 | KotCzarny | freemangordon: do it |
| 19:09.00 | vectis | yer, dsp1 |

| 19:12.21 | freemangordon | KotCzarny: on the other hand - why noone else want to do RE work? It is not *that* hard! |
| 19:12.33 | freemangordon | *wants |
| 19:12.37 | bencoh | freemangordon: it doesnt look like a critical part of maemo, but well if you have some time :) |
| 19:13.08 | KotCzarny | freemangordon: it is for someone who doesn't have tools/knowledge/experience |
| 19:13.18 | freemangordon | looks for volunteers to do RE job, with my help :) |
| 19:13.32 | KotCzarny | freemangordon: make a wiki thread |
| 19:13.37 | KotCzarny | i mean tmo thread |
| 19:13.46 | freemangordon | KotCzarny: hmm, might work |

| 19:14.16 | KotCzarny | on another note, my usb audio card claims to suck 500mA, yet, usb meter only shows ~30mA |
| 19:14.31 | KotCzarny | now i need some gender bender for my n800 |
| 19:14.48 | freemangordon | KotCzarny: connect headphones to it and raise the volume up |
| 19:15.05 | freemangordon | low-resistance ones |
| 19:15.07 | KotCzarny | i've connected it to stereo box |
| 19:15.34 | KotCzarny | but i know that it can eat more |
| 19:15.41 | freemangordon | that is why only 30 mA |
| 19:15.53 | KotCzarny | still, nice to know i can connect it to n800 and use as a grabber card |
| 19:16.07 | KotCzarny | without external power |
| 19:16.24 | freemangordon | doesn't it require CPU resources? |
| 19:16.38 | KotCzarny | dont know, what for? |

| 19:18.26 | vectis | hmm, do I need to reboot? |
| 19:18.32 | KotCzarny | vectis, nope |
| 19:18.48 | freemangordon | no idea, I am under impression USB is not the most effective when it comes to low CPU usage |
| 19:18.53 | vectis | still no go........... |

| 19:20.28 | bencoh | freemangordon: hm no |
| 19:20.57 | freemangordon | wait, wait, why assembly? |
| 19:21.16 | bencoh | because ... there is no C compiler for our target :D |

| 20:26.53 | Luke-Jr | "You need a kernel of at least 2.6.32 for NPTL support!" |

| 23:01.34 | Vajb | heh, all that audio talk here made me think, is there frequency response measurement software for n900? |
| 23:01.51 | KotCzarny | most likely yes |
| 23:01.55 | Vajb | tho i guess n900 mic quality wouldn't be enough |
| 23:03.11 | Vajb | also i just noticed that yappari has disconnected and wont connect again |
| 23:03.55 | Vajb | just checking to see if there is an update, but ham is taking her time....as usually |
| 23:04.54 | Vajb | btw KotCzarny, most likely yes for ap or insufficient mic quality? |
| 23:05.12 | KotCzarny | for fft display/finder |
| 23:06.01 | KotCzarny | http://maemo.org/downloads/product/Maemo5/tuner/ |
| 23:06.11 | KotCzarny | hmm |
| 23:06.16 | KotCzarny | wrong way, scratch that |
| 23:10.54 | KotCzarny | hmm |
| 23:13.41 | Vajb | cool, update fixed yappari |
| 23:14.02 | KotCzarny | http://talk.maemo.org/showthread.php?p=1343610 |
| 23:17.43 | bencoh | I wouldnt worry too much about it not being "good enoug" (well, it's probably terrible anyway :p) ... people do fft/audio measurements with an iphone/ipad these days |
| 23:18.39 | KotCzarny | you can always connect external mic of better quality |
| 23:19.20 | bencoh | or do a clean calibration (white noise / pink noise) to get the response curve of the mic |
| 23:19.40 | KotCzarny | that's assuming it's linear over volume/freq |
