You all know how I hate to take time away from the usual chatter with an actual problem, but here goes :-)
Has anyone else noticed bad sound choppiness since installing/upgrading to 9.2? I have two systems with this problem, one using the stock 2.4.22-21 kernel and AC97 sound and one using -mm with i810 sound, both using ARTS. artswrapper is suid, "run sound server with realtime priority" is checked in kcontrol (note that I actually use XFce4, not KDE).
XMMS is of course the app where I notice the problem (since GAIM is the
only other program that is allowed to make noise and it doesn't make
much). On stock-21/AC97 desktop, the "use realtime priority" flag is
set, and true to the warning, I've experienced a system lockup under
heavy load when XMMS was playing. On the 21-mm/i810 system, XMMS's "use
realtime priority" flag is not checked (system lockups are more annoying
on a laptop when there's no network accessibility).
I don't recall if the AC97 desktop is on OSS or ALSA, but the i810 laptop is on OSS since the 9.2 upgrade; it was rock-solid and generally perfect on ALSA for 9.1, but with 9.2 ALSA sounds were drowned in static and frequently played at the wrong frequency.
Any ideas? I'm sure I don't need to mention how annoying choppy music and system lockups are, especially when I'm the only hardcore Linux fanatic^H^H^H^H^H^H^Huser in the building.
Con Kolivas wrote about how renicing X to -10, as is currently done by default, can cause choppiness in the 2.6 kernels and, further in the thread, he recommends not doing it for any kernel. Don't know if this will help your situation but might be a heads up. His subsequent post also details how to change this setting.
