FYI, after a few IRC discussions with Markus, we've discovered that turning off the memory part of Gnome's System Monitor applet, would get rid of the skips. I believe the problem is that both sysctl and the sound drivers are Giant-locked, and so there is some contention. An easy way to reproduce these skips is to run `while true; do sysctl vm.vmtotal; done`, while playing an mp3. So, it would be nice to have giant-free sysctl and/or sound drivers.. :) Bye -- Suleiman Souhlal | ssouhlal_at_vt.edu The FreeBSD Project | ssouhlal_at_FreeBSD.orgReceived on Thu Sep 09 2004 - 04:48:04 UTC
