Bluetooth on RasPi3B+ not working

[BoblK54]

Update with the Allo Boss DAC set

I don't see anything suspicious in the startup log.

To troubleshoot the issue described in your OP "After turning Bluetooth On in Audio Config the system becomes unresponsive" try the following.

1. Remove Allo Boss dac from Pi
2. Start with fresh 761 image
3. Boot up
4. Turn on Bluetooth renderer in Audio Config

If system becomes unresponsive do the following:

1. Power Off/On
2. Examine the Moode startup log and see if it is complete. There should be a last log entry "...Ready".

Code:

moodeutl -l

The Bluetooth is functioning properly without the Allo Boss DAC.   I'm going to power everything down, install the DAC and see what happens.  I'll report back on what happens.
