Finding the Discord Sound Device

How the TranscriptOMatic should operate is, to connect to Discord voice using a dedicated Discord account for this purpose. During sessions, the Discord client (Legcord) will join the discord voice session. No microphone or speaker will be attached to the device. 

Finding the system's audio sinks

Checking for the system's audio sinks: 

pactl list short sinks

The result should look something like this:

mela@Cox:~ $ pactl list short sinks
35	auto_null	PipeWire	float32le 2ch 48000Hz	SUSPENDED

Finding the Discord sound device

After joining a Discord voice channel, checking for the Discord system sound device:

pactl list short sink-inputs

The result should be something like: 

mela@Cox:~ $ pactl list short sink-inputs
184	35	183	PipeWire	float32le 2ch 48000Hz

Creating a persistent monitor and a persistent sink. 

pactl load-module module-null-sink \
  sink_name=discord_sink \
  sink_properties=device.description=DiscordSink

You need to be quick after joining a voice channel. If the channel is silent, or the sink will go away quickly. 

pactl move-sink-input $(pactl list short sink-inputs | awk '{print $1}') discord_sink

Controlling the result: 

pactl list short sinks

The result should look something like this: IDLE instead of SUSPENDED.

mela@Cox:~ $ pactl list short sinks
199	discord_sink	PipeWire	float32le 2ch 48000Hz	IDLE

Getting the sound monitor source: 

pactl list short sources

 The result should look something like this: 

mela@Cox:~ $ pactl list short sources
199	discord_sink.monitor	PipeWire	float32le 2ch 48000Hz	IDLE
