Re: [LAD] Tascam US 122

if you have another usb controller, try to use it, I remember that one
controller doesnt work well with my tascam.
by controller I mean uhci or ohci.

My tascam (428) work well under ubuntu with a rtkernel or a non rt one.

Maybe you use an rtkernel with threaded isr and bad priority for your usb
irq handler. That could delay your tascam usb frame too much.
try with a generic kernel at first if you get sound without jack. If it work
then you will need to tweak rt priority.
