Sound choppy when switching scaling_gov

Sound choppy when switching scaling_gov

[Jonas Diemer]

Hi!

I am experiencing choppy sound playback with xmms. For example, when I
keep switching workspaces in my WindowManager, the sound is nearly not
usable. But also during normal work, mp3 playback is somewhat chopy.

This only occurs after I change the scaling_gov. Not after every change
though. If it happens, and I change the scaling gov again, sound
eventually is ok again.

I have a Pentium III 1.13GHz Laptop with a snd_intel8x0 soundchip. The
CPU (should) run at 733Mhz in powersave, so mp3 playback should be ok...

My Kernel is 2.6.2 (haven't tried the new one yet).

regards
Jonas

Does re-nicing the xmms process to a higher priority fix it? I had this
same problem, and re-nicing fixed it (well, hack-fixed it). I think
someone made mention of new 2.6 features like pre-emption, or the like
fixing it. Though, I'm a kernel newb, so that maybe incorrect.
