Red Hat Bugzilla – Bug 368901
Static on macbook pro with kernel 22.214.171.124-21
Last modified: 2008-01-15 22:36:11 EST
Description of problem:
After upgrading to kernel-126.96.36.199-21.fc7 on a second gen macbook pro, there is
a constant static/popping in the left channel audio. Also, the volume controls
are strange: the surround control is used to control attached speakers while
both the front and surround controls are used to control the onboard speakers
(used to be main/master and front).
Version-Release number of selected component (if applicable):
This was observed in Fedora 7 running kernel-188.8.131.52-21.fc7.
Steps to Reproduce:
1. Boot the laptop.
2. Play sound.
Static/popping in right channel. Volume controls incorrect.
Sound should play without distortion. Volume controls should be less confusing.
This effectively breaks sound playback for me. scsconfig.log attached.
Created attachment 249601 [details]
For clarification, the static is in the left channel as first stated in the bug
report. Sorry for the confusion.
Confusingly, after I booted into windows last night and booted linux again, the
distortion is gone.
I've filed a bug against Fedora 8 for this issue. See bug 380991.
