Hmm - blacklist the wifi drivers? I understand that even when you're not
connected, they will still regularly scan for signals. I understand this
can take time and is not RT-friendly at all.
I have a dual-core netbook (non-RT kernel, it's borrowed). During the
day, it sits on my desk at work and plays music from a USB drive thru my
UCA-202 USB soundcard. When I close up at the end of the day, JACK will
show 9-11 xruns.

just for completeness:
after checking out the scarlett 18i8 with another system (a
dual-core-netbook)
i have some not so nice drop-outs in playback, which not seem to be related
to any latency settings. (-
tried to debug a bit, but could not find any errors in kernel- or device
logs;
does anyone know a good practice how to filter this?
thanks james for that hint.
