Description of problem:
Probably just another report of a problem with soundcard detection
with Fedora Core 2 � Linux Kernel 2.6

I guess the following will be understandable enough without further

The following audio device was detected:

Vendor: VIA Technologies
Model: VT8233/A/8235/8237 AC97 Audio Controller
Module: snd-via82xx

Try to play test sound and:

Automatic detection of the sound card did not work.  Audio will not be
available on the system.  Please click OK to continue.

The motherboard is a Shuttle AV49VN with the above VIA onboard sound,
of course.

Complete, fresh installation of Fedora Core 2.

Soundcard detected perfectly by Red Hat Linux 9 and Fedora Core 1 (Yum
upgrade from RH9).

Believe it is to do with switch from OSS to ALSA, but have not yet
found good, clear, convincing  description of how to get sound working.

Version-Release number of selected component (if applicable):

How reproducible: Always

Steps to Reproduce:
1.> System Settings
2.> Soundcard Detection
3.> Play test sound

Actual Results:  No sound, mplayer just shows video without sound, no
audio streaming

Expected Results:  Sound from both speakers one after the other then
together etc etc

That's the correct driver, so it appears something is wrong with the
driver code.
Comment 2 Robert Tucker 2004-06-09 08:37:58 EDT
Listing of /etc/modproce.conf:

alias eth0 via-rhine
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-via82xx
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd

Is this OK?
Comment 3 Robert Tucker 2004-06-09 08:39:11 EDT
Sorry, that was /etc/modprobe.conf
Comment 4 Robert Tucker 2004-06-09 12:49:37 EDT
Have found that there were (zero) settings in “Volume Control” panel
that needed changing (should have checked there first I guess, but
with the test sound not playing.... )

CD's and MPlayer now seem to play OK, but the test sound and
RealPlayer play with a sort of (quite audible) scratchy sound in the
