[alsa-devel] Aureon 7.1 Firewire supported by ALSA ?
by Michael Gerdau 04 May '07

04 May '07

Hi list, looking for an external (USB or Firewire) interface to record at least a single stereo 44.1kHz/24bit S/P-DIF signal I've come across the Aureon 7.1 Firewire but have not been able to find out whether it is already supported by ALSA. Another option would be the Aureon 5.1 USB MKII but according to the specs it is 16bit only. However when feeding S/P-DIF with a stereo 44.1kHz/24bit would the driver be recognize that and give me that signal unaltered or would it be trimmed to 16bit ? [Or is my understanding of S/P-DIF just plain wrong and such a signal would not go through the box at all ?] Any advice welcome, best, Michael -- Technosis GmbH, Geschäftsführer: Michael Gerdau, Tobias Dittmar Sitz Hamburg; HRB 89145 Amtsgericht Hamburg Vote against SPAM - see http://www.politik-digital.de/spam/ Michael Gerdau email: mgd(a)technosis.de GPG-keys available on request or at public keyserver

[alsa-devel] [PATCH] multi-channel playback and capture fixes for stac92xx codecs
by Steve Longerbeam 04 May '07

04 May '07

Hi, I have picked up where Matt Porter left off on stac92xx HDA codec devel. I've been working with the 9200, 9221, 9202, 9250, and 9205 codecs, and I found some problems with muti-channel playback on 922x and 9205. Also a problem with input mux selection for codecs with more than one configured input pin. I've tested the attached patch on all the above listed codecs. Steve

[alsa-devel] support for Medion laptops

Hi, I installed Ubuntu Feisty a few days ago and my sound card driver doesn't work anymore.

[alsa-devel] dmix does not mix small files??
by Prabhu Sivaraja 03 May '07

03 May '07

Hi, I've been stuck on this dmix problem for the past week and have tried everything under the sun. Please any help or comment is much appreciated. Thanks a lot. Background info. ----------------------- In my ALSA driver I have thread that keeps track of hw_ptr(dmix) appl_ptr(for all other cases) and copies the incoming data from kernal buffer into device circular buffer(which is monitored by the device). I allocate 64KB kernal buffer in my module_init function . (See allocation below) snd_pcm_lib_preallocate_pages_for_all(pcm, SNDRV_DMA_TYPE_CONTINUOUS, snd_dma_continuous_data(GFP_KERNEL), 64*1024 , 64*1024); So I monitor this kernal buffer and copy data from this to my device circular buffer which is also 64KB. My period size is defined as 32KB. (See below) substream->runtime->hw.period_bytes_min = 1024*32; substream->runtime->hw.period_bytes_max = 1024*32; substream->runtime->hw.periods_min = 2; substream->runtime->hw.periods_max = 2; My asound.conf file pcm.mix { type dmix ipc_key 1024 slave { pcm "hw:0,0" rate 48000 } } pcm.!default { type plug slave.pcm "mix" } Everything was working fine until I noticed something weird. When I am playing a long wav file by invoking aplay and then try and play another small wav file simultaneously, the second file never gets mixed if the file is less than 64KB(my buffer size). If the second file is larger than 64KB then the second file gets mixed with the first one as it should since I am using dmix plugin. So in order to debug this I tried to decrease my period_size = 4KB but when I do this my hw_ptr never moves. My question. 1. Why do you think a file smaller than 64KB does not get mixed. (Obviously it has something to do with my buffer size but I dont get why?) 2. When I decrease my period_size to 4KB while keeping my buffer size at 64KB, why doesnt my hw_ptr move? 3. How else would I debug this? Thanks in advance. I would really appreciate any help. Regards Prabhu.

Hi Pieter, > Are you interested in joining the FFADO project? (short into: FFADO = > new FreeBoB = drivers for FireWire Audio Interfaces / www.ffado.org). > I have absolutely zero experience in firewire audio and firewire in general to be honest, but the project does sound interesting. > To be frank/direct here, I think that ALSA is better 'completed' with > FFADO support than with driver support for obsolete cards. But of course > I'm a little biased here :). Be as Frank as you want, I totally agree with you :) The thing is, I have limited time and experience (I have written one ALSA driver). Although supporting older hardware doesn't bring a whole lot to the project, it does provide me with a training ground so I can be of greater use in the future. I can work at my own pace on an area that nobody else will be working on. I can improve my skills without stepping on other people's toes. Your project sounds interesting but I don't feel I have the knowledge to keep up on a project like this. This is why I'm messing around with this stuff, so that I can do some 'real work' some day soon ;) regards, Ash =
