I don't recall making any big changes to my headless linux system, but all of a sudden I can't get MC26 to actually output through any available interface. When I play a file, it starts up fine and appears to be playing through the interface but I get no audio through my DAC. I tried switching through all other possible audio interfaces, hardware/USB/direct (stopping and restarting play every time), I even tried through the onboard computer speaker, with the same result - previously these had all worked. None of these actions threw any overt error messages.
The DAC works fine through the default gnome music app. I can stream local files to remote MC instances without problem. I also tried several reboots, turning off all services associated with MC and just loading a fresh instance through vnc. System is fully updated/upgraded. A clean re-install didn't fix the problem.
I've attached the log, basically it records me sending an mp3 for playback through my default hw DAC interface then stopping after a few seconds.
Any help appreciated, thanks.
