I was going through kernel traffic and read the article on the Maestro Driver problems.. I'm having very similar problems on my Dell i5000e laptop. The symtoms are: When I play MP3's, on an otherwise unloaded system, I notice progressive noisiness.. The longer it plays, (5-60 minutes), the stronger these artifacts are. It's like a constant high-frequency twirping and very annoying. When I have xmms 'seek' around, that tends to cause it to start introducing those artifacts.. If I stop the MP3 player and restart it, the artifacts go away completely, though they come back again. A second symptom is that occasionally a channel drops out; either left or right. Thse tends to happen on 'song boundries'. IE, times when the sound buffer is switched before the chip finishes sending it.
