Description Jussi Eloranta 2007-04-08 13:32:29 EDT
Description of problem:

After intial install on a macbook pro (intel), I got no audio. After playing with kmix, I was finally
able to get it to work. It looks like the channels are somehow setup incorrectly. Let me know, what
additional info I can provide on this. BTW after installing updates, this did not work either
(I recall that there was alsa update). 

Version-Release number of selected component (if applicable):

How reproducible:

Install FC6 on macbook pro and try to use the audio device.

Steps to Reproduce:
Actual results:

Expected results:

Please run system-config-soundcard, generate a log (/root/scsconfig.log) and
attach it here (when sound works and when it doesn't)

Comment 4 Jussi Eloranta 2007-04-10 11:59:59 EDT
BTW here is what I did with kmix to get audio:

THe output panel:

The "the plug; side" needs to be checked and the volume
setting here seems to affect the volume. This was not checked
by default. Also PCM seems to control volume.

The switches panel:

"Line in as output" must be checked (not checked by default). Otherwise
no sound.

Okay, I'll add it to alsa-utils. Thanks!
Comment 6 Martin Stransky 2007-05-16 10:16:23 EDT
added to CVS.
Comment 7 Fedora Update System 2007-05-21 18:25:09 EDT
alsa-utils-1.0.14-0.2.rc1.fc6 has been pushed for fc6, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
