Some ac97 chips do ONLY play 48000 Hz. It might be feasible to do a crude
x6 to get a 8kHz rate for the 8kHz uLaw our /dev/audio is supposed to support
(our AC97 code should maybe do this if no 8kHz native mode is around),
but it definitely is out of the scope of the kernel to do a filtered
interpolation that would make 48000/44100 enjoyable.
This was discussed a few months ago on one of our lists.
