Something appears to be borked in the ALSA arena. There's no actual volume coming out of the system, and 'alsamixer' is insisting that the volume slider only goes from 0 to 10% or so, no further. However, experimentation shows that the volume slider in 'xine' *does* affect the 'Amp-Out vals' lines, and alsamixer has *no* effect on what 'Amp-Out vals' lists.
A diff of alsa-info.sh for the two kernels shows them being identical, so I'm only attaching one copy.
Hm, there shouldn't be a change regarding the volume control. There can be an issue about PCM stream, e.g. in commit eb541337b7a43822fce7d0c9d967ee149b2d9a96 ALSA: hda - Make converter setups sticky
To be sure, could you try to revert it? If it doesn't help but still you get strange volume behavior, please get alsa-info.sh output at different volume levels for comparison.
thanks,
Takashi
