>Description:
When recording audio with the pcm device driver, there is continuous static in the audio.  The "real" audio is also present, the static acompanies it (on both channels).

AD_WAIT_INIT FAILED 1002 0xff

Installed devices:
pcm0: <OPTi931> at io 0x534 irq 5 drq 0:1 (1p/1r channels duplex)
