The problem
Trying to play audio via Bluetooth LE does not work. The audio source (Firefox/Tidal/Spotify) plays, but no audio gets transmitted/can be heard.
I recreated the same test setup on a new Google Pixel (from a friend) with Stock Android, and it worked perfectly the first time.
Steps to reproduce
For LinkBuds Open:
- Install Sony Sound Connect App
- Link your LinkBuds Open to the phone via bluetooth
- In the Sound Connect App, enable Bluetooth LE mode
- In the android settings, enable Bluetooth LE for the LinkBuds
- Try to play any audio
Technical details
I installed the Sony Sound Connect app and activated BTLE. I activated BTLE in the Bluetooth settings. I started an audio source in Firefox/Spotify/Tidal, the audio "played" but did not sound from any speaker.
I recreated the same on a new Google Pixel (from a friend) with Stock Android, and it worked perfectly the first time.
I tested this with my Sony LinkBuds Open. These are BTLE compatible. The LinkBuds support Bluetooth 5.3, AAC, LC3/LE Audio, Google Fast Pair, Microsoft Swift Pair and Multipoint.
This issue peristed after my upgrade from /e/OS a15-3.0.1-official to a15-3.1.4-official.
Changing Developer Settings did not help either, I tried with the following:
- Enable BTLE Broadcast UI Preview
- Bypass BTLE allowlist
- Bypass BTLE hardware offload
- BT AVRCP version 1.5->1.6
- BT MAP version 1.2->1.4
The tests from above were made with default dev-settings on both devices.
