This is a duplicate of the ticket #20431. The description and the analysis of the issue is already there. The error is here since 4 versions (was caused by the another refactor of sound backend back in the March 2021). It still here in the version 6.1.28 147628 and 6.1.29 147791, so I opened this duplicate.
Quick description here: after the host output device changes from Speaker to Bluetooth, then back to Speaker and then once again to BT, the sound output from VBox is lost. Other application from the host still can use the BT as output, but VBox can only use the Speaker after that. The only remedy is to restart or to save and restore the VM, but this only gives one single more short for the BT. After that the whole situation repeats itself.
