No sound on

drewhead · 01-17-2006, 08:46 PM

I've been building a new PC from newegg parts and can't seem to get sound working. It's a Asus A8N-Premium board that has the NVidia CK804 with ALC850 chip on board. I've compiled 2.6.15 with what I believe are th neccessary modules, run alsaconfig, and I'm not getting any sound. After several nights with my good friend google I am more turned around now than knowledgeable and amd not sure where I should be looking for the problem.

dmesg shows some errors:

Code:

Advanced Linux Sound Architecture Driver Version 1.0.10rc3 (Mon Nov 07 13:30:21 2005 UTC).
ALSA device list:
  No soundcards found.

Odd,

Code:

lspci -vv (relevant cut)

seems to know about it...

later in dmesg I get

Code:

and some more of that later.

Here's output from a script grabbed off alas.org that I think will have the answers to the other relevant questions.

Anyone see anything or know anything to help here? Anyone have this board working?

chrisortiz · 01-17-2006, 11:18 PM

did you run alsamixer and alsactl store?

also try typing

Code:

cat /dev/urandom > /dev/dsp

if ths sound is working you will get static

You've probably already done those, but its all i can think of.

what do you get when you type "lsmod |grep snd" ?

stevielawson · 01-18-2006, 03:53 AM

I'm assuming you're running Slack 10.2. If so, I had a similar problem (no soundcard detected by alsaconf) after I'd done a full upgrade through Swaret (which installed very latest alsa drivers etc).
I think it's an issue with the new alsa drivers and these Intel AC97 sound cards.
I found that by reverting to the original alsa drivers/etc on the 10.2 install disc, then re-running 'alsaconf' and 'alsactl store', my soundcard (same kind as yours judging by your output above) was detected, configured and gave me perfect sound.
I'm only a newbie myself so I can't honestly say this will definitely work - just that it worked for me.
Good luck!

mrapathy · 01-18-2006, 04:31 AM

do you have kernel modules installed?

check /lib/modules directory and do a lsmod to make sure they are loading. if you installed new kernel recently reinstall your nvidia nforce drivers.

I have an Asus A8N-SLI same sound chip. I used the test26.s kernal and installed the files off of cd2 in dir linux-2.6.13 ie the alsa-driver-1.0.9b_2.6.13-i486-1.tgz file

alsa may need additional configuration maybe new build or install the alsa.

I found the sound chip gave good sound but when playing doom3 the system choked I tried playing quake3 and ran into big problems. went to install creative labs emu10k1 card in pci found out pci slots didnt work.

month and new mobo later using creative labs emu10k1 card in pci slot. everything running great.

Thanks for the replies: Various answers

Yes, startup is restoring my settings properly across boots. Yes I scrolled all the way to the right to make sure I turned the volumn up on every setting.

Nothing audible at all.

Yes, I am on 10.2. The forum lost my login between register and my first attempt to post. My subject was a bit more descriptive (including 10.2) the first go around. I think I let form auto complete fool me the second go around.

Well... I can't use the drives from the install disk as they aren't for the new kernel I compiled. I will give a reinstallpkg of the lib and util's, a reconfigure to see what happens.

Barring that I suppose I can go grab the latest off of alsa-project and build myself.

Updates later this evening (EST)

BCarey · 01-18-2006, 05:07 PM

Try recompiling alsa. I find that I need to do that every time I compile my kernel. If the sources from alsa website don't work, try the one from slack sources.

drewhead · 01-18-2006, 09:28 PM

Well, if I was going rebuilding alsa I figured I might as well be on the latest kernel. So I went and grabbed 2.6.15.1 on a whim and rebuilt the kernel. While I was double checking my options I noticed that soundcore was being complied in the kernel not as a module. Setting to to compile as a module with my rebuilt kernel and another pass through alsaconf and I have sound. It's only the center channel and sub of this 5.1 system, and then only out the Analog port (not the optical that is also hooked up and works fine in the XP dual boot option of this machine) but I suppose I'll start looking now for config options to get the setting right now. Why-O-Why is it always the little things.

Thanks for all the responses anyway guys.
