Red Hat Bugzilla – Bug 75807
No sound with SB Live
Last modified: 2007-04-18 12:47:30 EDT
Description of Problem:
After performing a clean install of RH 8.0 I lost sound, even though sndconfig
appears to have correctly identified and loaded the necessary modules for my
sound card. lsmod generates the following output:

/etc/modules.conf includes the following line:
alias sound-slot-0 emu10k1
as well as related pre-load and post-remove directives
Version-Release number of selected component (if applicable):
Clean install of RH 8.0
Steps to Reproduce:
1. install RH 8.0
Sound card worked just fine under a previous installation of RH 7.2
sndconfig correctly detects the sound card and offers to "test" the sound, but
when clicking on the test button, no sound is produced.
are you using something like the digital out ?
I think I may have duplicated this. I have a machine that I just installed 8.0
on with a SB Live and a built in Ensoniq ES1371 [AudioPCI-97] (which I've never
gotten to work...hence the SB Live). I can't get modules for the card to load
and the SB Live does not appear in the output of lspci which I think is most
weird. Worked fine in 7.3.
Sorry...my error. Definately detect the sound card. Just get no sound. Please
Have you got a USB webcam attached to your machine? If you disconnect it and
reboot, does sound work after a modprobe emu10k1?
If so see bug 69945 and bug 77178 for problem descriptions.
Have you tried to load the driver manually? While root,
type modprobe emu10k1 and then see if sound starts working.
Also probably related to bug 75015. It looks like kudzu us having a problem
with USB audio devices and breaks the sound configuration on reboot. This
includes webcams with an inbuilt microphone.
Closing as here has been no activity following the very sensible comment about
the webcam problem
