A2DP profile not available until I disconnect and reconnect bluetooth

This is a recurrent issue but does not happen all the time.

I have a Sony WH-1000XM4. When I connect the device to bluetooth, sometimes A2DP is not available. I have to disconnect the headset and connect it again.

Relevant portion from pactl list | grep -i hsp.

I did check this: https://wiki.archlinux.org/title/Blueto … PulseAudio but the solutions are from 2019! Also I am using pipewire - GNOME 47 on Wayland.

[nightcore@arch ~]$ ps -e | grep -i pulse
   1584 ?        00:00:24 pipewire-pulse

Any assistance is appreciated.

Re: A2DP profile not available until I disconnect and reconnect bluetooth

Seems an issue with the headset, as stated on the wiki, some devices require a reconnection or pressing the volume / play buttons to enable the A2DP profile.

You can try the other solutions listed there but they usually don't work when I have tried them.
