Noises when turning off (known issue)

Referring to the well-known “feature”, cited also in the documentation,
the suggested workaround for the " Electric Noise when Quad Cortex is turned Off" problem is to go in STADBY before, so the audio outputs are disabled.
It works… but my question is: couldn’t a firmware update manage to also disable those same outputs right before powering off the QC?

Great idea! Also they could be muted so powering the QC on would’nt be a problem either.

Or as an alternative, couldn’t they add to the opened menu window one more option “STANDBY+SHUTDOWN” ?
