Vol 0% (stuck)

I was playing Rock 7 at 95 bpm for about 20 minutes through the stereo 1/4" outputs and suddenly the volume went to 0% (not the headphone volume, the main volume).

The volume knob is ineffectual.

Power cycle didn’t help. Restore default settings didn’t work.

Please help! What do I do? I didn’t find any similar issue on the forum. Firmware is 1.8.5

i unplugged it for a while (30 minutes?) and when i turned it back on it was back to normal
