list-audio-devices

name	list-audio-devices
description	List Pipewire audio sinks and sources with their IDs, descriptions, default-status, and current state. Use when the user asks "what mics/speakers are connected", needs IDs to feed into other skills, or is debugging why an expected device is missing.

List Audio Devices

Enumerate every Pipewire sink (output) and source (input) currently visible to Wireplumber, plus which one is the default.

Primary commands

Prefer wpctl (Wireplumber CLI) — cleaner output and aligns with how preference rules are written.

wpctl status

For machine-parsable output:

wpctl status --json 2>/dev/null || pw-dump

What to surface to the user

For each sink/source:

• ID (the numeric ID wpctl uses)
• node.name (stable identifier — what rules match against)
• node.description (human-readable)
• Whether it is the current default (marked with * in wpctl status)
• Mute / volume state if relevant to the question

Detecting node.name for rule writing

When the user wants a rule based on a device, get the canonical node.name (this is what Wireplumber matches on, not the description):

wpctl inspect <id> | grep -E 'node\.(name|description)|device\.product\.name'

Notes

• Bluetooth devices appear/disappear with connection state — if a device the user expects is missing, suggest checking bluetoothctl devices Connected.
• USB device IDs change across reconnects; node.name is stable enough for rules in most cases. For absolute stability, match on device.product.name or node.nick.
