After playing tune on Phasor, get a bit of noise when testing Phasor

Repro:

  • mb-audit v1.1 (preview 0.2)
  • do 'Music Test' for a few seconds (perhaps until it uses the AY noise channel?)
  • ESC to exit, then do 'Audit & Diagnostics'
  • the MB-C (s4) makes no extra noise
  • the Phasor (s1) make ~1s of noise before saying 'Classic Adventure'
  • NB. doesn't happen everytime

Still happens at 18e9fc8, and during soak testing at component = 0x10, ie. during Check6522().
But noise stops after DetectSubunits().

Makes sense, since DetectSubunits() calls DetectAY8913(), which does Init6522ForAY(), resulting in a AY RESET for both the AYs attached to that 6522.
