[LAU] rtirq configuration with external USB DAC?

Hi

I have a realtime audio server running mpd with an external DAC connected to a
USB2 (full-speed) port.

I am in doubt as to how the rtirq configuration should be at best, in
particular the entries:

RTIRQ_NAME_LIST=
RTIRQ_NON_THREADED=
RTIRQ_HIGH_LIST=

Thanks in advance for you help.
Regards
