Newer blheli firmware creates own buzzer

Ahoy,

I've had this happen on two quads now... I flash BF3.2... and I upgrade the escs (via blheli configurator) to the latest stable (non-rc) release...

When I trigger the buzzer then (via an aux switch), I get multiple tones.. I get the buzzer connected to the FC, and the escs are alarming too.... When I go back one version on the escs, it disappears.

Is there a value I can modify around thing? I can't find any tutes on it but I'm happy to just be pointed in the right direction...

Also, with BF3.2, there's no option for failsafe anymore, just failsafe on switch... Does this mean a failsafe is activated by default?

Thanks!
