Description

The Linux/FreeBSD audio sink help suggests pactl info | grep Source, which can return a microphone name. Using it as audio_sink causes audio capture to fail.

The existing pacmd list-sinks | grep "name:" command is kept. The incorrect Source lookup is replaced with pactl get-default-sink in the Web UI and documentation.

Screenshot

No layout changes.
