Coming to a v4 near you soon:
- Power button colors as per above post (including flashing red for error and blue for null audio)
- Error messages on failed to start audio drivers suppressed - except in the one case where you actually press the power button and it fails.
- Failed to start errors shown in the power button tooltip.
- Error messages in options dialog suppressed.
- “Failed to load” message on the audio ports page if the current driver couldn’t be loaded.
