Thank you. Seems working now. But there are 2 minor problems.
1. Sound, played through PA-EQ into Bluetooth headset cuts out beginning of the sound, maybe 500ms. So when a short notification plays, only a tail of it is heard. When music is playing from a freshly opened app, beginning of a song (500ms or so) cuts out, but when next song of the same player plays - everything is fine. Does PA-EQ need time to engage? Is there a way around it?
2. One of my BT headsets doesn't appear as an option when saving a profile in PA-EQ. One device is actually connected, but a previously connected device is shown when saving a preset in PA-EQ.
In the attached picture, LBT-PAR500 is connected, but two if the previously connected SOUNDPEATS Q35 are shown.
Also when I try to overwrite a preset with the same BT device, it shows that BT device twice. What does that mean? Should the duplicate checkbox be checked?
