Well, all sort from consumer grade to a bit betterones. I have to admit
that I never tried a high end chipset.

Currently I am using:

But the most is due the really bad code quality of alsa.

For example the localizing problem. I use tu have a locale that has the
"," as decimal divider. Now, I have to write floating point values in
.asound with a "," instead of a "." to get parsed but then, the code
behind the parser does not know what to do with the ",".

Another problem are the kernel panics that happens very often within
alsa. The best what I get was about one hour between panics. Usual I get
panics and oops after two minutes.
