If I set Jack parameters in Qjackctl any lower than
1024 I get Xrun
mayhem. (at 44100) I have also tried this running from consoles as root
and it does not seem to make much difference. Am I expecting too much?
Did you switch on DMA for hard disc accesses?
To do that a command like this needs to be executed:
# hdparm -d 1 /dev/hda
