Hi,
I've some seriuos problems with alsa and my audio chip, a VIA
Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio
Controller) (rev 10).
First of all, sometimes audio isn't working at all at boot time (it
dies?): I've to reload alsa (sudo alsa reload) manually.
Furthermore, alsa driver (intel-hda) is very unstable and it sometimes
goes in crash randomly.
I've this kind of problem with every previous Ubuntu version, and the
audio works fine in M$ Windows XP.
So, it's time to try solving this annoying issue with this audio chip :)
Note that when alsa is up and running, dmesg floods me there's
something wrong with alsa:

I've tried with alsa backports, but it seems that nothing is changed.

What I have to do to fix these problems in a permanent way (if
possible, without change audio card)?
Thank you in advance
