cs46xx bug on alpha

The cs46xx driver seems to compile, install, and load fine on alpha, and
the mixer (alsamixer) appears to work fine.  When trying to play a .wav
file with aplay though, I get this message repeatedly:
    May  9 10:11:47 draal kernel: ALSA pcm_lib.c:116: Unexpected
    hw_pointer value (stream = 0, delta: -2679, max jitter = 2756):
    wrong interrupt acknowledge?

    error (DMA or IRQ trouble?)

My /proc/interrupts:

My /proc/dma:

This is kernel 2.4.17 with a Hercules Game Theater XP.

Any ideas?

P.S. I'm surprised to see many more channels in alsamixer than I thought
the OSS driver supported.  Does the alsa driver really do 3D and support
all the extra inputs on this card?  (YAY!)

Cheers,
