restoring media volume after tss "warnings/dings"

I ran into this kind of issue on a recent trip and my solution was to activate the car's voice assistant by pressing the button on the steering wheel (but not holding down, which activates your phone's assistant) then say something like "cancel" which I assume isn't actually a voice command to make it do nothing. The audio state will be restored to normal after the car stops listening for the voice prompt.

And to be clear, what I was experiencing was definitely a bug that only occurs when one of the car's warning alerts sounds at the same time that a connected android auto phone is playing navigation instructions. I wish I knew who to report this kind of thing to because it's easily reproducible and is highly disruptive when it occurs if you don't know the workaround.

 

@radsaq Haha I did the same thing. I press on the "voice" button on the steering and then cancel.
It is a bug - but it is a difficult bug to eliminate; also my friends who use Car Play do not have this issue.

 

I tried to look up the audio architecture of Android Auto and was unable to verify how it works. However, I assume that this is an indication that separate navigation and music audio streams are the phone, and the car is thus allowed to mix and route them however it likes and in this case it is totally muting the one audio stream. (AA uses wifi direct and not bluetooth when it's used wirelessly, so there's plenty of bandwidth for multiple streams.)

It would be interesting if an Apple user could chime in and indicate whether the same bug happens with CarPlay.
