Bluetooth wireless headset sometimes cannot automatically select A2DP

When the headset is automatically connected to the computer,
sometimes it will automatically use A2DP Profile,
and sometimes it will automatically use HFP (then the sound will be very poor).

Sincere question., how can I set it to keep using A2DP Profile forever?

Re: Bluetooth wireless headset sometimes cannot automatically select A2DP

Sometimes depends on signal strength/an issue in which order your headset reports it's capabilities.

In any case your sound daemon is what does this, and both pulse and pipewire/wireplumber have functions to enforce this, what are you using here? Do you happen to have a mic/ a potential mic using application active? Mics only work with the HFP profile, if that's what's enforcing the switch because you want to use the mic there's nothing you can do about that.

In any case depending on your daemon see: https://wiki.archlinux.org/title/PipeWi … _selection or https://www.freedesktop.org/wiki/Softwa … oth-policy
