Sound output switches away from bluetooth soon after connecting

HI all,

I’m having an issue where when my Pixel Buds connect to bluetooth, the sound output will switch back to line-out sooner after the earphones connect. Then to get them to output correctly, I have to either disconnect and re-connect the earphones, or if that doesn’t work, then unpair and re-pair. I’ve recently done some distro-hopping (Kubuntu / Fedora Workstation / openSUSE Tumbleweed) and didn’t encounter this issue on any of those?

Admittedly, I’m a little lost with this one, I’m hoping one of you might have some decent suggestions?

Many thanks for any help given, it’s very much appreciated
