Public bug reported:
Issue with Sony MDR-1ABT Bluetooth headphones:
Once paired, the headphones will be connected automatically whenever they are
switched on. However when connected this way, only the HSP/HFP profile will
work and trying to change to A2DP in sound settings does nothing.
If the headphones are then manually disconnected and reconnected from Bluetooth
settings, they will initially use HSP/HFP but then selecting A2DP in sound
settings will successfully make them use A2DP.
