As listening, the distortions are really quite heavy, maybe I just live with them for too long that I usually don't notice all of them. There is always some sort of quick choppines, slowdown or a *click* every 5-30 seconds (even when there are still some times, when audio plays fine for more than a minute, so the distortions are not constant). The system is FreeBSD 6.0-CURRENT #0: Wed Dec 8 02:43:42 CET 2004 Machine is AMD Athlon(tm) XP 3200+ (Barton), KT600-based ABIT KV7. Sound onboard 'VT8233/33A/8235/8237 AC97 Enhanced Audio Controller' (I can possibly test with SB Live!, but it will take a few days). SCHED_4BSD, no PREEMPTION, apic enabled, no WITNESS/INVARIANTS. I will try to remove apic during next stage of testing.
