[arm-allstar] 2 nodes on pi, audio goes out 1 node

[Al Beard]

Hi David,
What if you use a 64bit linux system?

Being a new-comer I was disappointed the ARM-Allstar image wasn't 64bit.

Also, what if you use different kinds of USB FOB?
I'm about to use the Creative Sound Blaster Play 3! because it is stereo
in and out and "hopefully" available world-wide.
