Pipewire device selection isn't actually a device

[ProjectPatatoe]

Description

Mumble Pipewire output/input is not giving option to select device and instead shows the channels (Mono/Stereo). It seems to be automatically selecting the first device on the recording list.

Steps to reproduce

1. Select Pipewire in Input->System
2. Select Pipewire in Output->System

Mumble version

1.4.230

Mumble component

Client

OS

Linux

Reproducible?

Yes

Additional information

This is on Steam Deck. SteamOS (Arch,kde)

I don't have pipewire on any other system so I don't know if this a SteamOS thing or a Pipewire thing

Relevant log output

No response

This is specific to our implementation, I'll add a proper device selector.

Cool to see Mumble running on a Steam Deck!

I realized I forgot to mention, switching to Pulseaudio is a workaround for anyone else looking to get this working without messing around with tricking the device order and the such.

I am facing this as well on mumble-git ("1.6.0") on commit b60c9dd6e3215f82a3986cf886689fbf404efba6

The functionality is implemented in libcrossaudio, which will be used in Mumble to replace our current audio backend implementations.
