Greetings,
I've been working with Ardour3 on my laptop, a machine with an AMD
Turion X2 CPU and an nVidia 8200M integrated video chipset. Recently
I started monitoring my test recordings through the headphone output
of my UA25 and I notice that when I move the mouse it creates
scratchy sounds, though QJackCtl reports no xruns and my recordings
are unaffected. I verified the problem with Ardour2 and Mixbus. It
doesn't occur when I use the integrate audio chipset (snd-hda-intel,
wahoo).
Running 'cat /proc/interrupts' reports that usb1/usb3 share
interrupt 17 and usb2/usb4 share interrupt 16. I've tried switching
ports around but that didn't get rid of the noise. Any further
suggestions ?
Do you see any difference if you toggle the ground lift switch at
the
back?
Cheers,
S.M.
Best,
dp
