low volume with Jabra bluetooth headphones
I've got Jabra Elite Active 75t bluetooth headphones and the audio volume is really low on Linux Desktop in comparison when connected to my Android phone. I made sure that both the application playback volume and the device output volume is set to 100% in pavucontrol
but the real output volume is still really low.
Please, can you advise how to debug the issues? I would like to provide more information to get this fixed.
I'm running Fedora 34 with the following packages:
- pipewire-0.3.29-2.fc34.x86_64
- bluez-5.58-2.fc34.x86_64
The configuration is default except for the following two tweaks:
$ /etc/pipewire/media-session.d/bluez-monitor.conf
properties = {
bluez5.msbc-support = true
bluez5.sbc-xq-support = true
}
$ cat /etc/systemd/system/bluetooth.service.d/override.conf
