I'd like to enquire about reliability issues I've had on LE with Bluetooth audio output.
What happens is that the first time I use a Bluetooth headset all is well, but once I've finished watching whatever and switch off the headset to put it on charge the LE audio output seems to break. The symptom is that all future audio output is completely silent. This includes HDMI, analogue, and Bluetooth outputs, even when cycling through them to try and cause whatever audio backend LE uses to restart. It also includes when the original headset is reconnected fully.
Well, I say silent, but not completely. UI and media audio doesn't play at all, but the "null" background sound is still audible, including the audio you hear with the "Send low volume noise" setting.
So far the only workarounds I've come across is either hard-reboot LE or cycle through half a dozen (or more) media files. -- The latter option will sometimes cause the LE audio output to kind of restart itself, in that a loud burst of backlogged UI sounds play in parallel, and the media's audio plays as normal until the next time the Bluetooth headset is disconnected.
This isn't quite the same as LE Settings Addon Crashes, though getting the Plugable USB Bluetooth adapter solved that. -- Using a USB Bluetooth adapter also solved a slightly different issue I experienced with the Pi's built-in Bluetooth device whereby audio output would play fine over Bluetooth for a random duration (anything from a few seconds to 10ish minutes) then go completely silent as per my current issue.
Would there be any recommendations for stabilizing Bluetooth audio output, or would this be a real issue?
This issue seems to impact LE versions 9.0 and 9.2 equally. My Pi is model 3 B+. My Kodi log is here: 2019-12-09 19:06:49.560 T:1937637392 NOTICE: ---------------------------------- - Pastebin.com
