Description Michel Alexandre Salim 2007-09-16 01:01:47 EDT

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 Alexandre Salim 2007-09-16 01:03:39 EDT

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 08:46:11 EDT

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 19:22:15 EDT

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
