A couple things I have noticed as of today. I experienced intermittent Bluetooth audio when connected to my vehicle. A quick disconnect and reconnect seemed to have fixed the problem.
Also when connecting to my other vehicle via USB audio, the sound remained through the phones audio speakers until I disconnected and reconnected.
Something to look out for.
Please try steps below to see if it helps.
- Turn off Bluetooth
- Go to settings > apps > Click on arrow next "Your apps" > Select show system apps and press ok
- Go to Bluetooth app > storage and clear data and cache.
- Turn on Bluetooth
Please note this will remove your existing devices and may need pairing them back.
