I try to run xwax on ubuntustudio 8.10 on a Panasonic
CF-T2 subnotebook
(1Ghz/512MB). Everytime I start real time audio apps like jack the graphic
gets very slow and freezes for some seconds, also the audio playback is
like timestretched and sounds filtered.
I guess it has something to do with interrupts shared by graphic and sound
(sound comes from a Maya44 USB sound card).
Can anybody give me a hint how to check or alter interrupt settings or do
you have any other ideas...?!
Most computers have more then one usb port. And these usb ports sit on
different irq's, I doubt it that all of them are shared with the graphics.
How do you know which usb port uses which irq?
Check the output of "lsusb" and "cat /proc/interrupts" to see where
you audio-
device is connected and which irq that port has.
Have fun,
