[PROBLEM] BlueTooth Output Very Low

[Tim Curtis]

Hi

I have a Pi 4B 4GB running Moode 8.1.1 (64 bit version) and a HifBerry DAC+ Pro and its working great on both the headphone jack and of course the DAC to a Bose Companion 50 speaker system and sounds great. I want to try and stream this Moode system now to a Bose Flex Bluetooth speaker which I am having issues with.

I set up the BT via the BlueZ config and can pair and connect the speaker but the BT output to the speaker is extremely low ( in fact you can only hear it very faintly if you place the speaker to your ear.) There is also a lot of back ground noise and hiss but I guess this is because the Moode output volume is set to 100 and the speaker volume set to max. I have tried all sorts of changes including removing the DAC completely and configuring just the PI 4B but still no joy. I have checked the Alsamixer and its only has the DAC output listed which I would expect and this is all good. I also tried various other BT devices ( apple Airpods, Jabras BT headset ) and still the same issue.
Has anyone else had issues with BT on the Moode 8.1.1 ?

I just ran a quick test with an Anker Soundcore BT speaker and no issues with volume however when changing from MPD audio output -> Bluetooth back to -> Local the BlueZ Config screen crashes :-0

This is due to a bug involving a missing library and is fixed in upcoming moOde 8.1.2 (soon).

For renderer issues where the UI is broken run one of the commands below to restart and reset the renderer.

Code:
