Description of Issue

It used to be that if I paused the music then the Beolab 50 speakers would go to standby after their USB signal time out expired. Which is what I also want.

I stop (pause) roon playing music and after the timeout the speakers go to sleep. This is the legacy and desired use case.

Since the latest build the Beolab speakers stay alive indefinitely. Seems like the nucleus keeps sending 0 values to the speakers via USB ??? And thereby keeping the speakers alive.

Please revert this behaviour to the previous situation.

Because now if I stop the music playing my speakers never go to sleep anymore. This is very energy inefficient.

Hmmm. Sometimes it works as before. And sometimes the speakers stay alive as if there is still a USB signal being send.
Can you please check if the USB implementation has changed?

Problem disappeared. Don’t know why.
