Problems with sound disruptions can usually be traced to running with WITNESS and/or INVARIANTS compiled into your kernel. These debugging options cause enough interrupt latency to cause sound problems. Even setting the sysctl debug.witness_watch=0 (I guess its debug.witness.watch=0 now) will usually clear the issue right away, or reduce the disruptions significantly (for that boot only). If the sysctl doesn't exist then you don't have WITNESS. -- Doug White | FreeBSD: The Power to Serve dwhite_at_gumbysoft.com | www.FreeBSD.orgReceived on Thu Oct 21 2004 - 15:25:56 UTC
