i have been able to use alsa-driven utilities reliably on the stock
FC2 2.6.5 kernel, although on the recent upgrade to the 2.6.6* series
i have not been able to get any sound out of alsa-driven utilities
I have issues with alsa and the 2.6.6* series, too.
In short:
- under KDE, I have no sound if I boot a 2.6.6* kernel, and any
application which is sound-related either gives no sound or hang
completely (must be killed).
- under Gnome (my default), all system sounds are distorted / changed,
and I experiment ramdom and _very_ frequent lock ups and freezes.
All this goes away if I reboot wit the original 2.6.5 FC2 kernel.
There's something broken in the 2.6.6* kernels; it affects only a few
particular hardware configurations (and in different ways). Maybe it's a
bunch of different problems... who knows.
Up to now, I haven't found any clue, nor any advice on how to debug this
in more detail.
