Comment 1 Walter Dorninger 2004-04-02 00:55:54 EST
I upgraded from Fedora CORE1 (final) to Fedoara CORE2 (test2) and have
the same problem

The detection of the soundcard works fine but there is no sound at all
and the progs accessing the sound devices do not work.

Vendor: Intel Corp.
Model: 82801DB AC'97 Audio Controller
Kernel Module: snd-intel8x0

Comment 2 Walter Dorninger 2004-04-02 00:59:10 EST
btw. sound worked in Fedora CORE1
Comment 3 Walter Dorninger 2004-04-02 02:18:39 EST
For some reason the kernel module snd-intel8x0 does not get loaded
automatically. After calling "/sbin/modprobe snd-intel8x0" the sound
works. To make it permanent (so it loads the module ons tartup) add
the line "/sbin/modprobe snd-intel8x0" in /etc/rc.local.

btw - I detected a similar problem regarding my USB devices (USB
optical Mouse). I had to load uhci-hcd also to make my USB mouse work.

82801DB AC'97 Audio Controller sound card was detected, but no sound
at all. After I set all mixer controls to the maximum i can hear sound
Comment 5 Joshua Daniel Franklin 2004-04-10 18:12:54 EDT
I actually have an nforce chipset, but it uses the snd_intel8x0 
module. I had no sound until I un-muted all the channels using  
alsamixer from alsa-utils. I also have to do this after rebooting 
for some reason. 
Comment 6 Walter Dorninger 2004-04-11 04:36:00 EDT
fyi - I have to run the soundcard detection and then /sbin/modprobe
snd-intel8x0 and then it works...
Comment 7 Mikel Ward 2004-04-30 07:20:21 EDT
This is probably because /etc/modules.conf has the wrong entry, and so
the appropriate module is not loaded.

It has:
alias sound-slot-0 i810_audio

I suspect it should have:
alias sound-slot-0 snd_intel8x0

Not sure whether it's kudzu's or system-config-soundcard's job to
update this after upgrading from OSS to ALSA or when the user changes
his sound card.
Comment 8 Mikel Ward 2004-05-04 05:18:11 EDT
After making appropriate changes to /etc/modprobe.conf, my soundcard
module is now loaded but sound is muted.  This can be worked around by
running system-config-soundcard (which seems to reset the mixer levels)
or running alsamixer and unmuting the PCM channel.

This is the same problem mentioned in many comments here, but perhaps
not the problem mentioned by the original bug reporter.  These symptoms
look more like a problem with initscripts or alsa not saving the mixer
state at reboot (or something establishing bad defaults on boot).
