It's nice to see the aureal driver has been merged
upstream finally. Many thanks to Manuel and Jeff.

Thats because the AC97 mixer names. There are some rumors on the ALSA
list to change that someday, but that is code outside of the Aureal 
driver.

I'll try to investigate this, but i have no problem regarding this with
my Yamaha DB50XG.

This warning happens due to a timing issue in the mpu401 code. I
submitted a patch about May / April of the present year, but the changes
regarding that delay loop wheren't accepted. I guess because it would
affect almost any MPU401 compatible card. I'll try to push this patch in
again.
The driver worked well on my computer even with this warning showing up
on only time (on first midi event), but now i see that there is
something to be fixed :D
