Both version 1.1.14b and 1.1.15 claim the sample rate
is locked at 48KHz. With version 1.1.14a however, I can
use any sample rate.
I use Linux 2.4.7. I have a AOpen AK33 mainboard (VIA
KT 133 north bridge, VIA 686A south bridge). The
documentation mentions an AD1885 codec chip.
I've included the dmesg info for versions 1.1.15 en
1.1.14a, and the output of the diagnostic program
(which was the same for both driver versions).
