Sound card detected, everything checks out... but no sound.

I've been trying to get my intel digital audio working, and I'm baffled, the wikis don't have an answer for this.

Everything the wiki says checks out, but nothing will play.

[root@harpo jeremy]# lsmod | grep '^snd'

[root@..]#

As far as I can tell, all that says that it should be working, but it's not.
When I try and assign a device (I seem to have a choice between oss and alsa) and test the sound in Xorg, I get this:

audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open resource for writing.

aplay seems to run, but no sound comes out.
Any suggestions?

Re: Sound card detected, everything checks out... but no sound.

I'm having the same problem with an AD198x intel sound card in a Thinkpad T61.  Many people are having similar problems with ubuntu, but the possible solutions don't apply to arch.  I'm curious what machine you have and why your are showing two devices.

Have you found a solution?

Re: Sound card detected, everything checks out... but no sound.

Does analog work?

You need to configure arch to use device1 (digital) by default. maybe put it for pcm 48000Hz too.

Check asound.conf in wiki and alsa site.

Maybe try to play sounds with mplayer and change sound hardware from 0,0 ... 0,1 ... and so on.

Re: Sound card detected, everything checks out... but no sound.

Hi.

I got mine to work. Its sort of a hack.

I followed the instructions in  http://alsa.opensrc.org/index.php/AlsaCVS and got the driver to compile but not the alsa-utils, So I installed the alsa-utils from testing with pacman -S -d alsa-utils and it now works. Don't forget to unmute the mixer with alsamixer.

Re: Sound card detected, everything checks out... but no sound.

You should also make sure to add alsa to rc.conf.

If you don't do that, no matter what you mute / unmute - it may default to muted when you reboot.  Unless you use alsactl to load / store your settings manually...but then that's what adding alsa to rc.conf will do for you

Hope this helps.

Re: Sound card detected, everything checks out... but no sound.

got mine to work as well. 

I installed the standard package from arch's repos, then

* hg clone http://hg-mirror.alsa-project.org/alsa-driver alsa-driver
* build driver according to readme
* added alsa to modules in rc.conf
* unmuted
* restarted (didn't really need to do this, but it felt good)

What's hg? I can't find it in the repositories.

Thanks

hg is 'mercurial'
it's like cvs or svn

Thanks!

Installing the cvs drivers over the repository drivers works great!
