How long have you been using 2.6.15? The ALSA drivers are in the kernel. > Well, it has, but in just the past week I've noticed very strange > audio performance problems.

It may just be that you've never used so much CPU before. There are kernel patches that substantially improve sound performance, or you can downgrade the kernel, but before resorting to drastic measures, make sure the problem is really in the kernel...

Try killing artsd and see if the problem goes away. In that case, probably increasing the priority of artsd should help. Alternatively, you can set up ALSA to use hardware mixing and KDE not to use artsd. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
