Using audio to optical (from computer) and connecting with optical (tos link) into tv connector seems to resolve the issue for many people? Because it seems that tv connector when connected with audio, shuts down per gain lower than x, whilst for tos link connection it stays active whenever any bit is coming through.
And it seems that audio to optical just send enough bits to keep it alive.
I’d try that since tv connector connection eats HA battery one third of a speed of BT connection. Which could be a factor if you have a ton of meetings.
