Diagnostics

audio_monitor_property_dump

The Windows project includes a diagnostic executable target named audio_monitor_property_dump.

This tool is not part of the public Flutter API. It exists to help inspect native endpoint properties while developing or debugging the Windows backend.

What it does

It dumps property keys and values for:

• capture endpoints
• render endpoints

This is useful for comparing endpoint state:

1. before enabling Listen to this device manually in Windows
2. after enabling it and selecting a playback device

When to use it

Use the dump tool when:

• a driver behaves differently on one machine
• the Sound Control Panel does not reflect the expected state
• you need to verify which endpoint properties changed
• you are debugging support for a new audio device

Typical workflow

1. Run audio_monitor_property_dump
2. Save the output
3. Enable or change Listen to this device manually in Sound Control Panel
4. Run audio_monitor_property_dump again
5. Compare both outputs

Important note

This tool is intended for diagnostics only. It should not be treated as a user-facing CLI or a stable contract for external automation.
