I have similar problems, except the disruptions only seem to occur during keyboard activity. I ran a cvsup while using mpg123 and had no problems, which is pretty impressive since the machine is a P133. However, even a small amount of typing causes noticeable audio glitches. This happens both with a ES1371 and an old SB16 ISA card. It seems I may also be losing keystrokes from the keyboard, though I haven't confirmed it's not a problem with the keyboard itself. - Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
