during the last days I finished to update my system to new release and new kernel, and after this I get no sound out of my hybrid.
I already made a test booting off a Knoppix live cd, and in that situation audio is fine so it is definitely not an hardware problem.
The nasty thing is that if I switch back to older kernel (18.104.22.168) I get no sound either, so it is not likely to be related to some faulty kernel modules
Last time Pluto switched kernel I had a similar problem, but it turned out that for some mysterious reason audio devices were not created anymore under /dev
This time audio devices seem to be there.
It sounds like new version of xine is making my life so miserable, but of course I may be wrong.
Has anyone experienced this behaviour, and (most important) has anyone some hint to let me get rid of this issue?
