I was towards the end of a marathon beat gridding session (the joys of old funk and disco records), just tweaking a playlist and all of a sudden tracks were not loading into the decks properly.
The track info loads, but there is no waveform and the track won’t play. I have done a transfer to my USB’s (checking 1 before I loaded the other) and tested in the Prime and all seems OK. Have made some changes to a playlist and synced them back to Engine DJ, all OK. But still no joy.
On a Macbook Air M1. Restarts all done. Have done a DB optimisation.
Not sure I want to backup the database just in case it backs up any issues. And annoyingly I was about 5 minutes from doing my post gridding session backup.
When I connect my bluetooth headphones to the Mac they connect in headset mode (essentially for making calls, so in Settings > Sound the input (mic) is set to my headphones
In this mode the headphones are in mono and this is what messes with Engine DJ.
When I load a track the track info loads but no waveform and it won’t play just like the issue you have.
Not sure exactly what the audio setting were when it started messing around, but I have just tinkered around in the output and input settings and everything is working again.
Thank you for the pointer. Might be a low priority bug for the devs to look at.
