bamsi Sorry for the confusion, GSConnect is a GNOME shell extension that comes with Onyx and gives KDE Connect support to the GNOME shell
As for the pulseaudio config file, we actually use Pipewire by default (and as such, pipewire-pulse as a stand-in)
There's a chance that it could be configurable in the VOIP software you use (I believe it's configurable in both Discord and Skype)
Out of curiosity, which VOIP software are you using that could potentially be the culprit?
