See bug report kern/16709 for my patch. Please apply the patch Michael speaks of here (in kern/16709). If you can't get it to apply, I can send you the patch. At any rate, the patch didn't work for me, although it did make xmms 1.0.1 usable from its GUI and 'scope' standpoint. Still hogs CPU. It's definitely an "xmms thing" because mpg123 only chews about 4% of my CPU playing any song on earth. But, xmms "didn't used to do this," (even on version 0.9.5.1) so there's something that's been committed to the pcm0 driver code that needs to be tracked down and speared.... -Jr -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | John Reynolds WCCG, CCE, Higher Levels of Abstraction | | Intel Corporation MS: CH6-210 Phone: 480-554-9092 pgr: 602-868-6512 | | jreynold@sedona.ch.intel.com http://www-aec.ch.intel.com/~jreynold/ | =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
