[alsa-devel] HDA Intel ALC885 - Need new or edited model option
by Constrabus Gegami 06 Jul '08

06 Jul '08

I need a new or edited model option for this card: HDA Intel card in Alienware m15x laptop That uses codec: ALC885 Detailed specifications on the card: http://www.alienware.com/Configurator_Pages/Details_Pages/Details_Page.aspx… alsa-info.sh genterated output: http://pastebin.ca/1061774 (i switched back to no model options before i ran the script, i dont know if it leaves behind anything or if it even matters) Jack Observations: -1x auto-sensing headphone jack -1x auto-sensing microphone jack All current available model options either present me with: -working switchable internal speakers with non working headphone jack -working switchable headphone jack with non working internal speakers -non working headphone jack and internal speakers -working non switchable internal speakers with non working heaphone -working non switchable headphones with non working speakers -no working sound What is needed: - working switchable internal speakers with working headphone and mic jack (preferably switchable) Distro: Gentoo amd64 using alsa driver package (not in kernel modules) I hope that this will benefit others as well as I. If any more information is needed, please email me. -- --Constrabus

[alsa-devel] EMU10K1 Problem. Im stumped.
by Travis Place 05 Jul '08

05 Jul '08

Just had a user on #alsa with an EMU10K1 problem. To summarize, the card shows up in linux (but doesnt work), yet the card works perfectly in windows. The correct modules are loading, but ALSA doesnt see the card. It had the user unload/reload snd-emu10k1 and check dmesg output, and the relevant result is as follows. EMU10K1_Audigy: probe of 0000:00:0a.0 failed with error -16 There complete alsa-info.sh output can be found at http://pastebin.ca/1062377 I have had the user run this both with and without the onboard AC97 card enabled (just to be sure). What seems odd to me, is that the card is at 00:0a.0 and the SB Live revision is showing as (rev 0a). Just doesnt look right to me.. The card is an Creative SBLive! 'SB0220'. I have one of these exact cards here, if its needed for testing, but its never caused me any issues. Anyway, any help would be appreciated. Thanks, Travis Place (wishie)

[alsa-devel] Sound distortions with Realtek ALC889A
by Matthias Dahl 04 Jul '08

04 Jul '08

Hello. Due to a hw defect, I recently bought a Gigabyte X48-DQ6 board which utilizes a Realtek ALC889A for sound output. At first glance everything seemed fine but during day-to-day use I figured that during playback of a 5.1 file, I've to turn up the volume quite a bit to match normal 2.0 playback or the volume levels of my old board (ADI1988B). And to make matters worse, the surround channel produces (static) noise on the center channel. If I mute every channel but the surround channel, the distortions are clearly hearable. During normal 5.1 playback, they are only hearable during scenes with a lot of talk or quieter scenes which is still very annoying unfortunately. Muting the surround channel also stops the distortions on the center channel. Also the model is not properly recognized, I've to pass model=6stack-dig to get all channels properly working with digital out. By the way, this is with a 2.6.26-rc7 x86_64 kernel running a alsa git checkout from last monday. I'd appreciate any help or hints I can get. Thanks in advance. Best regards, Matthias Dahl

Hi: im responing to: "If you have an unknown card, please mail the ID and board name to <alsa-devel[AT]alsa-project[DOT]org>, regardless of whether audio capture works or not, so that future versions of this driver know about your card." i have an ATI TV WONDER VE (PCI) card. im using slackware 12.1 with default kernel "root@cpu99:~# uname -a Linux cpu99 2.6.24.5-smp #2 SMP Wed Apr 30 13:41:38 CDT 2008 i686 AMD Athlon(tm) XP 2600+ AuthenticAMD GNU/Linux" im following this project here: http://www.domenech.org/bt878a-adc/alsa-e.htm if you wouldnt mind telling me which version of alsa and with what config settings to get that to work i would much appreciate it.

[alsa-devel] Alsa 32-64 bit issue
by Wolfgang Rosenauer 03 Jul '08

03 Jul '08

Hi, I'm new to to this list (and also Alsa) so please forgive me some newbie questions you probably find ;-) I have an application which does simple PCM output to Alsa. It works so far (if pulseaudio is not used but that's another issue). But if I try to run the app (which is compiled for 32bit) on a 64bit Linux system it fails at snd_pcm_start() with the following error: "DatenÃ¼bergabe unterbrochen (broken pipe)" So is that an app, system or kernel issue? Sound output from other 32bit applications (notably flash) works in general so I guess something in the app is broken? What could be the issue? Thanks, Wolfgang
