Red Hat Bugzilla – Bug 231749
New kernel kills audio
Last modified: 2007-11-30 17:11:58 EST
Description of problem:
My Intel motherboard has built-in ATI SB450 HDA Audio. When I run 2.6.19-
1.2911.6.5.fc6, Sound Detection shows that my PCM device, ALC 833 Analog,
vanishes. When I switch back to 2.6.18-1.2798.fc6, audi is perfect.
Somthing in the new kernel deletes the PCM and kills audio.
Version-Release number of selected component (if applicable):
Version numbers above.
Steps to Reproduce:
1.Boot with 2.6.19-- no PCM detected, no audio.
2.Boot with 2.6.18-- PCM detected and audio is good.
Internal audio card detected, but no PCM detected.
Soundcard Detection should detect audio card and PCM.
Please see bug 231414. Is your system the same?
