Any solutions? It certainly is a known problem as it's been here and been reported on since last week. However, nobody can seem to determine what circumstances cause these messages (like if you play a wave file, or start/stop an MP3, some sort of "event" like this). For me these messages pop up "randomly" while playing MP3s with xmms (not correlated to the beginning or ending of a song). So, who knows. My sound quality has not deteriorated in any way, but I'm sure these messages aren't a Good Thing(tm) to have in the long run seeing as how they weren't there 2 weeks ago. -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
