James, on my Ultra-24 (running snv_127 right now), I modified: /kernel/drv/audiohd.conf and reduced play-interrupts and record-interrupts to 50: play-interrupts=50; record-interrupts=50; I consistently encountered the static problem on many snv releases in the past, but have not seen it since I made this change. And this is after tens of hours of audio playing via the legacy Solaris audio interface.
