Description Ryan Schlesinger 2007-11-06 15:58:36 EST
Description of problem: 
After upgrading to kernel- 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-

How reproducible:

Steps to Reproduce:
1. Boot the laptop.
2. Play sound.
Actual results:
Static/popping in right channel.  Volume controls incorrect.

Expected results:
Sound should play without distortion.  Volume controls should be less confusing.

Additional info:
This effectively breaks sound playback for me.  scsconfig.log attached.

For clarification, the static is in the left channel as first stated in the bug
report.  Sorry for the confusion.
Comment 3 Ryan Schlesinger 2007-11-08 16:28:30 EST
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.
