Current setup:
Motherboard: M2A-VM has a connector for either ac97 or hd sound. I am
using ac97
Sound output: line output from computer to tv.
OS: Fedora 8 with all updates
Tested for sound with the following:
1) When using kcontrol to test sound, it fails with no apparent errors.
2) When using aplay to test sound, it fails with no apparent errors.
You could try running with the -v option,
verbose.

Also run dmesg
immediately after
the failure to see if it logged any messages.
No apparent messages from dmesg
3) When using system-config-soundcard, the sound works.
This indicates a configuration issue. There would be no sound if alsa
hadn't recognized your card.
4) cat'ing a wav file to /dev/dsp works.
OSS emulation, using alsa, another indication that sound is almost working.
In searching for an answer, one comment was made about pulseaudio causing
problems so I removed it. Sound test 1 and 2 from above still fail and
test 3 and 4 still work.
I re-installed pulseaudio but it did not install as many rpms as the
remove process deleted.
Unfortunately, I know very little about troubleshooting audio problems,
so any help will be greatly appreciated.
I would have added configuration files but I do not know which ones would
be revelant.
Let me know what additional information needs to be supplied.
Thanks,
David
Can you run the shell script at
http://hg.alsa-project.org/alsa/raw-file/tip/alsa-info.sh
and post the link to the output back to the list. It will scan your
system for sound
related information and post a summary to a web site. It will give you
a link to the
information on that web site.

Everything looks good. Your sound should be working. I did notice that
your
default device is digital instead of analog/PCM. Digital playback is
disabled in your alsactl file.
1. defaults.pcm.card 0
2. defaults.pcm.device 1 <---------------- analog would be 0
here
3. defaults.ctl.card 0
4.
5.
6. Aplay/Arecord output
7. ------------

9. APLAY

I'm not sure how it got set, but it would cause the symptoms you are seeing.
You can test by playing as follows
aplay -v -D plughw:0,0 some.wav
If the test succeeds, you need to change this to be analog permanently.
You do it by editing /etc/asound.conf and changing the device to be 0
instead of 1 as above.
