Default Bug#497185: linux-image-2.6.26-1-686: sound volume randomly drops to low level, adjusting returns to original level

Package: linux-image-2.6.26-1-686
Version: 2.6.26-3
Severity: normal


Whenever headphones volume is above 70%, after a few moments, the volume
_audibly_ drops to a much lower level while alsamixer reports no volume
change. Increasing/Decreasing volume fixes the problem momentarily.

The problem only occurs with this new kernel version and occurs with any
set of headphones.

Hi,
The next release of Debian (6.0, code name Squeeze) will be based
on 2.6.32. Please test the current 2.6.32 from unstable/testing and tell
us whether the problem persists. If so, we should report it upstream
to the kernel.org developers.

The 2.6.32 kernel is available from packages.debian.org and can
be installed in both Debian stable, testing and unstable
installations.

Thanks,
Moritz
