Bluetooth audio does not play in car without reconnecting bluetooth

tdb · 8 April 2024 17:48

REPRODUCIBILITY: Always
OS VERSION: 4.5.0.25
HARDWARE: Xperia 10 III
UI LANGUAGE: English
REGRESSION: Not that I’m aware

DESCRIPTION:

When I start my car (Hyundai Ioniq Electric 2018), it automatically connects with my phone over Bluetooth. However audio plays from the phone’s speaker until I go to settings, disconnect the car’s bluetooth and let it reconnect. After that it works find, but having to do this every time is annoying.

PRECONDITIONS:

I’m not aware of any, but I haven’t tested this with any other cars.

STEPS TO REPRODUCE:

Start car
Wait a few seconds for bluetooth connection
Start music playback (from phone or from car, doesn’t matter)

EXPECTED RESULT:

Music plays from car’s speakers.

ACTUAL RESULT:

Music plays from phone’s speaker.

MODIFICATIONS:

I have a few native applications installed from unofficial sources (Pure Maps, OSM Scout Server, Sailtrix, DeaDBeef) plus some Android applications, but it seems unlikely that those would affect this issue.

ADDITIONAL INFORMATION:

On the first connection pacmd list-cards shows the car’s a2dp_sink profile as unavailable. On reconnect the profile is available and gets activated.

There doesn’t seem to be any way to attach files here when creating a new topic, so I’ll add logs later once I figure out how.

Still can’t find any button for attaching files. The upload button on the toolbar only works for images.

(Output from different programs was collected at different times so some things do not match, particularly the fdN strings in the object paths.)

Since I couldn’t attach the files, I’ve put them on my web server: https://www.tdb.fi/~tdb/tmp/sailfish_audio_problem_logs.zip

Let me know if there’s any other information I should gather.

Some additional data points:

Bluetooth audio works correctly with my Steelseries Arctis Pro Wireless headset and doesn’t need this reconnect dance
Behavior is the same with both the builtin media player and DeaDBeef
