As soon as I can get an [Asus USB BT500](https://www.asus.com/Networking/USB-BT500/) I will try that, as I suspect this issue is somehow related to the chip in the dongle. It seems like all dongles with the same chip has the same issue. The sound problem is probably (?) a secondary effect, but that is the most prominent effect.
