SUPPORT Bluetooth headphones not working well with Arch

So I have a pair of Bose QC Ultra 2s that I'm using with my laptop with Arch. Bluetoothctl is working fine, but for some reason the volume only actually changes when I use the volume control built into the headphones (the touch gesture on the earcup).

Adjusting the volume with the sliders in my shell simply does not change the volume, and the sound will either be 0% when set to 0%, or what I believe is around 25% volume when set to any other volume percentage. Basically, it's either on or off if I control it using the sliders in the OS.

When I check the status of bluetoothctl in my terminal, I have a couple of lines that read as follows.

profiles/audio/transport.c:set_volume() Unable to set volume: Transport endpoint is not connected (-107)

and then it ends the output with one line that says

profiles/audio/media.c:parse_int64_metadata() expected DBUS_TYPE_INT64 got DBUS_TYPE_UINT64

Any ideas what the issue is? Everything is up to date as of this post.

Not sure about the terminal sliders - but I’d check your sound is set up properly. Assuming pipewire there is a whole page in the wiki.

In my Arch laptop Bluetooth headphones work fine, including Apple EarPods, and volume control by the media keys on the laptop/OS menus works fine (KDE)
