WinTV Go and btaudio

[Neil Radisch <nradisch@xxxxxxxxxxxxx>]

sox -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp /dev/dsp

works but the audio crackles badly. Also my dmesg log
fills up with this:

btaudio: irq loop=1 risc=1, bits: OFLOW RISCI*
btaudio: irq loop=1 risc=2, bits: OFLOW RISCI*
btaudio: irq loop=1 risc=3, bits: OFLOW RISCI*
btaudio: irq loop=1 risc=4, bits: OFLOW RISCI*
btaudio: irq loop=1 risc=5, bits: OFLOW RISCI*

etc.....

System is a Soyo P4VDA (P4X266A chip set) running a 2.4Ghz P4

Any ideas what the problem might be?
