[alsa-devel] hda-intel via codec on optical sound
by AL13N 04 Oct '09

04 Oct '09

I have posted this, but no reaction on alsa-user... (i'm not on the alsa-devel list) Maybe this is a bug somewhere, that is what i wish to know. I have a onboard hda_intel card. it has 2 codes and is split in 2 parts: * via * atihdmi I want to have sound in the optical output SPDIF/TOSLINK whatever you want to call it. hdanalyzer shows 2 digital pins: 0x20 ext SPDIF ATAPI 0x21 ext SPDIF Optical but both are marked as 'not present'. the "2d card has only one pin and one audio out" on the motherboard there is an internal SPDIF connector, which may be the ATAPI one. I believe that the SPDIF Optical is the correct one. Why is it not present? is that something software related? or is the audio chip broken? that is what i really want to know at this point. is it broken or can it be fixed? mail sent to alsa-user: -------------------------------------------------------------------------------------------------- i have only an optical link to surround set, (which has worked before) to test out. the toslink looks red on the surround endpoint. the surround system always says: "no data" (analog stereo or DD or DTS causes it to show a diff text) when i play something, (be it stereo, DD or DTS sample) at iec958 , the /proc/asound/card0/pcm1p/sub0/status shows effectively that the sound IS running there. I've set all soundlevels to 75% and unmuted everything. i've looked at the codec#0 file and that may give something: node 0x21 (digital with optical connector) shows as not present. it looks like there are on seperate models for the VIA codec. how would i go solve this?

[alsa-devel] [PATCH] sscape: remove MIDI instances counting with limit ULONG_MAX
by Krzysztof Helt 04 Oct '09

04 Oct '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> There is no sense to limit open MIDI connections with limit as high as ULONG_MAX. Also, convert more messages to use the snd_printk. Correct few old and misleading comments as well.

Re: [alsa-devel] Asterisk and ALSA/Jack

Hi, I want to use Asterisk with ALSA / Jack audio. I tried the next configurations : 1 ) app_jack.so -> does not work. 2 ) chan_alsa.so without jackd started my .asoundrc : pcm.!default { type hw card 1 } pcm.jack1 { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } pcm.jack1b { type plug device jack1b server linux slave { pcm "jack1" rate 8000 format FLOAT channels 2 } } ctl.mixer0 { type hw card 1 } in alsa.conf : input_device=default output_device=default That works fine. 3 ) chan_alsa.so with jackd started Jackd launch command : jackd --port-max 16 --realtime --no-mlock -d alsa --playback hw:1,0 --capture hw:1,0 --rate 8000 --period 1024 --shorts --inchannels 2 --outchannels 2 --dither triangular & my .asoundrc : pcm.!default { type plug slave { pcm "jack1" rate 8000 format FLOAT channels 2 } } pcm.jack1 { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } pcm.jack1b { type plug device jack1b server linux slave { pcm "jack1" rate 8000 format FLOAT channels 2 } } ctl.mixer0 { type hw card 1 } in alsa.conf : input_device=default output_device=default It doesn't work.

What's the best component to report this bug against? kernel? Those keys are a 'HAL' thing. Until recently there has been a website by the HAL developer with detailed instructions. Search for 'HAL Quirk Site' on Google to view the site in Google cache. The website was not updated for some time (http://www.mail-archive.com/pm-utils@lists.freedesktop.org/msg01594.html) and being obsolete, it was probably taken down. Your changes would need to make it eventually to the hal-info repository, http://cgit.freedesktop.org/hal-info/ Use the Freedesktop Bugzilla, product 'hal' and component 'hal-info' when reporting, https://bugs.freedesktop.org/enter_bug.cgi?product=hal Simos

[alsa-devel] big latency and buffering question
by Achim Herrmann 02 Oct '09

02 Oct '09

Hi all, I'm completely new to sound and ALSA development and I have to develop an application which is capturing periodically a small amount of audio data (e.g. 64 frames), doing some processing and doing playback of the result. I started with ALSA example "pcm.c" to see if ALSA can meet these requirements. During investigation i found out, that up to a choosen buffer size of 140ms, generated sine sound is fine. Below 140ms, sound is stuttering, independent of call method I'm using. For buffer size of 140ms I found out, that target buffer size is 6174 frames (at 44.1kHz sample rate), period size is 3087 frames and loop inside write_and_poll function is calculated every 70 ms and 3087 frames are written. Think this is doublebuffering then, right? But if I now choose a buffersize of 139 ms or lower, target buffer size and period size are always the same. So no double buffering anymore and sound is stuttering. So, currently I'm far away from goal. I'd like to have a buffer size of e.g. 128 frames (2ms). Thus, period size should be 64 frames and loop should be calculated every 1ms. (If necessary I would use Linux-RT) If I choose a buffersize of 2ms, sound is far away from being sine :-) - Can I use ALSA for a application described in first sentence above? - What do I have to change in pcm.c to be able to create a sine signal using a buffersize of e.g. 128 frames and a period size of 64 frames? Any hints are appreciated Thanks in advance Achim

[alsa-devel] [PATCH] ASoC: Improve the debugfs hierarchy

Change the way the debugfs entries are created: If the codec->dev is valid, than use: debugfs/asoc/{codec->name}.{dev_name(codec->dev)}/ if the codec->dev is NULL: debugfs/asoc/{codec->name}/ as root for the debugfs entries.
