New issue: I was erasing a Tape segment pressing Record and Down then Play when this occurred. Following what I thought was me erasing the Tape and then rewinding I returned to Live mode but no sound was getting in past In, nor in Nav mode.
I rebooted thinking that maybe the SDCard had finally frozen. Nope, same problem.
Turned off my rig for 5 minutes and restarted it and still no sound in Live or Nav.
Restarted while holding Down and Record to clear the tape and sound returned as normal (after mandatory reboot following this operation).
Now I’m trying to duplicate the issue so I can report on precisely what caused it and I’m not able to.
