Sorry--I have a UL30A also, but no sound problems to speak of. I am
running Kubuntu Maverick in the 64-bit iteration...are you running 32
or 64 bit?

(I have no idea if that would make any difference--I am simply seeking
to understand why your installation and mine seem so different).

Of course, KDE uses a somewhat different sound architecture--so
perhaps that is also a factor. You might run a live CD of Kubuntu and
see if that has the same symptoms...perhaps Phonon in KDE has a better
relationship with the sound?

Good luck.

David
