This is all done with tuned disks, lowlat and root access.

Yesterday I was having this problem. I also tested the sound quality of
native alsa vs jack by using two alsaplayers one connected to alsa and
one connected to jack.

While doing that I found that the output quality was exactly the same so
I assumed that it was the alsadriver that was at fault. However After
letting the machine and device cooldown while I slept and testing with
native alsa today the sound quality is crystal clear. When I test
through jack the quality is degraded. I assume that it is the demands
that jack places on the system that is causing the quality to degrade.

I have just gone down from 9 -> 6 screens in my virtual desktop and that
seems to have gone a long way towards cleaning the sound. Any ideas on
how I can tune x to give me those screens back? I currently use a
geforce2 with nvidia drivers. I'm holding out on getting a new video
card until the price of the new ATI has dropped.

Does anyone know how the support for that card is going?

Being on stage with the band in front of crowds shouting, "Get off! No!
We want normal music!", I think that was more like acting than anything
I've ever done.
