2012-06-28 05:22:50 Len Ovens description When running Jackd at lower latencies, there are three or four major xruns every minute or so. If the wireless is connected. If the wireless is disabled it gets much worse with an xrun every 5 seconds or so. As far as I know the tx is powered off at this point. If I modprobe -r ath9k, there are no xruns. I am not sure the wireless can be connected without causing problems, but when it is disabled and the tx turned off it should not interfere with anything. The module is able to do this if the wireless is dissabled and the machine rebooted, so there is a state when ath9k is first loaded that is fine. When the wireless is disabled it should go back to that state. For now, I have a script that unloads and reloads the kernel module for audio work. By the way, the xruns are worse with this version of the kernel than they were in precise (3.2 low latency kernel).
