Description Michel Lind 2007-09-16 05:01:47 UTC 
Description of problem:
On a Thinkpad T61, when using internal speakers only the left one produces any
sound (using gnome-volume-control, if the left speaker volume is set to zero, no
sound is produced). With headphones plugged into the audio output jack, sound
works normally

Version-Release number of selected component (if applicable):
alsa-lib-1.0.14-3.fc8

How reproducible:
Always

Steps to Reproduce:
1. Play a stereo audio file
  
Actual results:
With internal speakers, only left speaker outputs any sound

Expected results:
Both speakers should produce sound

Additional info:
Comment 1 Michel Lind 2007-09-16 05:03:39 UTC 
It appears that the problem disappears after toggling the speaker switch (in
gnome-volume-control) on and off. Will investigate if right speaker is always
disabled on startup
Comment 2 Martin Stransky 2007-09-19 12:46:11 UTC 
Aha, okay. Anyway, that could be a kernel issue (the speakers should be enabled
by drivers by default) so please reopen this bug for kernel (or report it to
ALSA project - www.alsa-project.org).
Comment 3 Jan Hutař 2007-10-20 23:22:15 UTC 
Both speakers works for me as expected on T61 using:

alsa-lib-1.0.15-0.4.rc3.fc8
kernel-2.6.23.1-23.fc8
