I follow a nearly identical flow several times a day to connect bluetooth headphones to my laptop.
- Turn on headphones
* Laptop connects immediately and uses the HSP/HFP mode (works!)
* Trying to select A2DP appears to work, but no audio will play
- Disconnect the headphones using the Bluetooth manager
- Reconnect the headphones using the Bluetooth manager
- Select A2DP, this now works.

Separately, many web videos will stop playing and refuse to play when the Bluetooth audio device is selected.
