	I'm not very familiar with the Sparc audio hardware, but that
sounds very much like a missed-interrupt problem. An i386 system of
mine exhibited precicely that behaviour when the sound device was
configured in the kernel for a different interrups than it actually
resided at. 
	What are your kernel config lines and boot-time fconfiguration
output for the audio device? Maybe we can compare them with those of
someone with working sound in a similar box.
