Description Alison Stewart 2005-06-20 03:32:27 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
After installing FC4 on a system with an Intel AC'97 sound card, sound didn't work.  We tried fiddling with alsamixer, but nothing was muted, all levels were normal.  Sound worked fine under Ubuntu, so we compared modules between Ubuntu and FC4.

Unloading the snd_intel8x0m module, then unloading and reloading the snd_intel8x0 module got sound working again.  We blacklisted the snd_intel8x0m module, and that fixed the problem.

Version-Release number of selected component (if applicable):
kernel-2.6.11-1.1369_FC4

How reproducible:
Always

Steps to Reproduce:
1. Install FC4
2. 
3.
  

Actual Results:  sound didn't work.

Expected Results:  sound should have worked.

I can confirm this with and hpze4900 with snd_intel8x0m module loaded. 
Blacklisting the module in the /etc/hotplug/blacklist file resolves the problem.

Please attach the output of running "sysreport"...thanks! 

Comment 5 Dave Jones 2005-07-15 21:13:29 UTC
[This comment has been added as a mass update for all FC4 kernel bugs.
 If you have migrated this bug from an FC3 bug today, ignore this comment.]

Please retest your problem with todays 2.6.12-1.1398_FC4 update.

If your problem involved being unable to boot, or some hardware not being
detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE*
installing any kernel updates.
If in doubt, you can recreate this file using..

mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak
mv /etc/modprobe.conf /etc/modprobe.conf.bak

Thank you.

If someone else can test the new update, that would be good -- I don't have time
right now to break my system again and fiddle with it.  :)

Comment 7 John W. Linville 2005-07-29 15:15:51 UTC
Still waiting on output of sysreport, and on results of testing the latest 
kernel update... 

Comment 8 John W. Linville 2005-09-16 18:35:30 UTC
Closed due to lack of response.  Please re-open when the requested information 
becomes available...thanks!
