Re: [orca-list] Configuring Pipewire

[Jason White <jason jasonjgw net>]

This is interesting. Removing and then re-inserting the USB audio device 
enabled Pipewire to detect it. At that point, I was able to use pactl 
set-default-sink (with the index number obtained from pactl list short 
sinks) to change the default output device.

I'm wondering whether Speech-Dispatcher might be bypassing Pipewire when 
loaded by gdm (or otherwise excluding the USB audio device from the 
Pipewire instance that I assume is loaded in the user session).
