Audio stops after DAC is turned off and on


I’ve noticed an issue when using my chord mojo dac.
If I pause a song and turn off the dac (to save battery) a message appears saying the dac is no longer available.
When I return a while later and turn on the mojo a message appears that it has picked up the mojo.
The music appears to be playing but audio is not being passed to the mojo. The mojo is still selected in the playback options.
Only a restart will fix the issue.
Also the main playback screen does not update unless I change the audio volume widget. That’s hos I can see the track time is increasing.
