Steps to reproduce
1. Trigger voice assistant using steering wheel voice button
2. Say something like "Play my spotify playlist called houses"
3. Assistant correctly opens spotify and plays the songs
4. After that steering wheel music controls (next/prev songs) are not working
@admin: Do you know more about this problem? I can't reproduce (no steering wheel with buttons in use).
@pres1o: Did the buttons work correct before? Do the buttons work if you start Spotify NOT using voice control? Did you try other programs with and without voice control? We have to clarify the source of this "switch off button control". It might the transport protocol, voice control, Spotify or Android Auto itself (they continue to alter the program all the time. What worked today doesn't work tomorrow and vice versa). Sorry to be no better helper, please keep us informed what you found out.
Bye for now Fred
@ap756 yes steering wheel buttons work normally before triggering voice assistant.
The type of voice search search doesn't matter, they stop working as soon as voice assistant is working
