Hi all,

I have a problem with my soundcard.

If I run the sound card detection tool my card is detected:
Vendor: Aureal Semiconductor
Model: Vortex 2
Module: snd-au8830

However I dont have any sound. If i run the volume control tool i get the following error:
Couldn't open mixer device /dev/sound/mixer

Actually there is no /dev/sound/mixer. I just have /dev/mixer

/sbin/lsmod has the following output:

I have installed:
kernel-module-alsa0.9.8
alsa-lib
alsa-driver
alsa-utils

Hope somebody can help.

ok, I could fixed the problems.

since it may be usefull to other people having troubles with sound, here is what I did:

The new ALSA release contains the Aureal drivers. So I downloaded the alsa-packages from freshrpms (kernel-module-alsa, alsa-utils, alsa-driver, alsa-lib).

Then I downloaded the alsa-tools-0.9.8.tar.bz2 (didnt find rpm) and ran the alsaconf script in the utils directory. This will modify the /etc/modules.conf. Actually IT (=the script, not me ) makes a bakup from modules.conf and overwrites /etc/modules.conf with alsa-stuff only! So I had to copy the not alsa-related but still important stuff (like nic, graphics modules) from the backup-file back into to new /etc/modules.conf.

After rebooting (or depmod -d) I could play sound, but didn't get anything through my speakers. I used alsamixer to enable mixer, cd playback and stuff. Then it worked.

Finally I added a group audio which owns all audio dev files, and added my users to that group.


Thanks to the guys @ #fedora irc, for pointing me into the right direction!
