It is now in my tree will push later tonight with your other patch.
Sorry for my tardiness. I really suck of late, but trying to get head
into it again :D

Hmm, right. Your memory is likely better than mine. I'll take another
look at that one - tho' I guess it should still be fixed at the alsa level.

OK, another mixer question now I've got you listening :D

https://bugs.mageia.org/attachment.cgi?id=1204 (alsa-info)

This has three "Master" controls (0-2). I'm not really sure what this
means! Can you shed some light on it (is it just something that is
better quirked in newer kernels?)
