[LAU] xrun problems. (Was Re: Introduction to Ardour 3.0 MIDI)

[david]

I have a UCA202, also. Make sure it's the *only* device attached to 
whatever USB controller you've hooked it to. USB sucks when multiple 
devices share a controller! On my setup, it wouldn't work correctly at 
all until I put it on its own USB port.

On my laptop, even with the wireless antenna turned off, the wireless 
driver period pops up and scans for networks. Of course, it finds none, 
but while it's interacting with the wireless hardware, it causes xruns. 
IIRC, some folk on the list said to blacklist the wireless module so it 
doesn't even get loaded?

I've also heard that the binary NVidia drivers do not cooperate with RT 
work.

I've glad you were able to make a Pengutronix kernel work. I couldn't 
make their kernel work at all. So far, the RT kernel in Aptosid seems to 
be working very well on my desktop PC, so I'm planning to try it on my 
laptop.
