Lately I have a strange behaviour:
I connect my N900 to my car via bluetooth for making calls on my cars MMI (Audi). After my N900 gets disconnected when I turn off my car all volume will be muted - not on profile "mute", but volume=0. This will be both on regular volume as well as using cabled headphones.

I did not experience this before the latest updates to T8.1, I don't know if this occured already on T8

Don't know if this happened to someone else before. Couldn't find any information.
