USB Audio Volume

[Doppelganger]

I just setup recalbox and I am using a USB audio dongle. It is working as it should but I cannot adjust volume through the software. It says volume is 0, even though it is not. Is there something I can do to fix this or am I stuck with adjusting volume on the speakers themselves?

That's a known issue, can't say we've been really investigating that one due to lack of time and devices to check the bug

Ok, thanks for answering. Knob adjustment it is.
