Trying to use Bluetooth as A2DP only device

I have a pair of bluetooth headphones which upon connection always use the HSP/HFP profile. This also happens every time I make a Skype call. However, I only want to use this as an A2DP device. I’d like to disable auto switching, or even lock out HSP/HFP all together. In RFTMing, I’ve looked at:

Perhaps I didn’t read these carefully enough, but I couldn’t find how to get it to do what I want. I also had a look at: /etc/pulse/

I’d be grateful for any ideas or suggestions.

Edit: The first thing is to check if the A2DP sink profile is available.

Hello @Philo-Phineas
Did you install all the bluetooth as per the wiki? Did you go through this setup?

It is available, the trouble is that I gneed to select it manually every time.

Did you add this to the file?

sudo nano /etc/pulse/


# automatically switch to newly-connected devices 
load-module module-switch-on-connect

Yes I added that.

Are you using bluetoothctl to try and connect and pair.

Yes, I went through those steps in a terminal… but I’m not sure why that will change anything, as it used HSP/HFP on connect, and there was no step to switch to A2DP. The other thing to knote is that I’ve been using KDE rather than gnome.

sudo systemctl status bluetooth

Have you looked at bluedevil which is a package to integrate into kde? Not sure if it’s any help?

Here are some tools to maybe help.

dmesg | grep -i bluetooth

See what modules are loaded.

lsmod | grep -i bluetooth

You can run btmon in a separate terminal while you’re scanning for your device and see if there are logs that contain e.g. the name of your device.


Use lsusb -v to find more information about the type of device that it is when it’s plugged in.

lsusb -v

See what bluetooth packages are installed

pacman -Qs blue

See what pulseaudio is installed.

pacman -Qs pulse
