Audio Output on Ubuntu 24.04 Not Working on Jabra Speak

[ska352]

Recently, my system got an upgrade from 22.04 to 24.04. Since then, Zoom can't output audio to my Jabra Speak 510.

* Music players, browsers, spotify can use the Jabra sucessfully. Not a general hardware support problem.

* Zoom can use the built-in speakers of the laptop successfully. Not a general audio problem with Zoom.

Since 24.04 (Noble Numbat), Pipewire is used as the audio backend system. So, I already played around with some settings here. The Zoom client for Linux seems to use PulseAudio which Pipewire supports with a compatibility layer (package pipewire-pulse). This is installed.

Has anybody faced something like this and has any pointers?
