EchoMuse v2.9.10

Reporting improvements, and a fix to on-device wake word scoring

Nothing changes about how your Echo listens or responds. This release is
worth taking mainly for what it adds to the dashboard.

What you get

• The Status tab now shows this Echo's temperature and how many of its CPU
  cores are awake, and warns if the chip ever starts limiting itself
  thermally. It idles around 33°C, so anything amber there is unusual.

• A second CPU core is kept awake. The Echo has four and parks the ones it
  is not using; the audio pipeline works to a tight deadline and does
  better when it is not sharing with everything else. Measured cost was
  0.3°C and no change in power behaviour worth mentioning.

• Amazon's Whole Home Audio service is switched off. It is the multi-room
  feature EchoMuse replaces, and nothing else on the device was using it.
  Frees roughly 20MB of memory, applied on this update and taking full
  effect after the Echo next restarts.

Fixed

• On-device wake word scoring (the experimental "Score on device" option)
  was comparing itself against the controller unfairly during playback.
  While audio is playing, the controller deliberately lowers the bar for
  hearing the wake word — the speaker drowns you out — and the Echo was
  not doing the same, so every interruption looked like the Echo had
  missed it. Both sides now use the same bar, and the comparison in the
  Activity tab reports how many turns were genuinely comparable rather
  than lumping the rest in as failures.

  If you do not use that option, this changes nothing for you.

Updating is safe and needs nothing from you. If an update ever goes wrong,
the Echo rolls back to its previous version on its own.
