No sound from Jabra 510 speaker after upgrade to 23.10

[Shaun Crampton]

My Jabra 510 speaker used to work in older releases of Ubuntu but, since upgrade to 23.10 and switch to pipewire, only the microphone works. If I select the speaker output in settings or directly in Zoom I hear nothing.

I found an upstream issue here: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1984. Some users report that pipewire master fixes the issue.

I tried creating a file /etc/pipewire/pipewire.conf and adding the configuration from that ticket:

context.properties = {
        default.clock.quantum = 2048
        default.clock.min-quantum = 1024
        default.clock.max-quantum = 4096
}

The Jabra speaker then started working in Zoom but the Ubuntu settings app showed no devices at all. I'm guessing that the quantum setting worked around the bug but creating the file overrode some other config that Ubuntu is relying on. It's not clear how to configure pipewire on ubuntu, upstream seems to use a different file layout.
