I'm stuck on this. I'm trying to use my Mbox 2 Micro as a soundcard on my Pi.
Linux Jesse recognises the device on asla but no sound comes out. It lights up and give an encouraging squelch like it used to indicating it's being driven. But I have nothing
I can't even remember the firmware I have on it. I'd like to get some help on testing it on linux. Somone here said even on 1.38 the sound output works (that's all I need).
Edit: I was able to get the firmware updater on my Win 10 machine and it told me I already had the correct firmware. Incidentally I tried to update anyway and ran in to the same problem as OP.
Still begs the question, why isn't audio coming out of the M Box 2 Micro from the Pi? It works fine on my Windows machine.
