The question was why is audio power spec is half that of DC on/off
capability.

** No it was not.


It is because the device stays on all the time and because the audio
waveform causes more heating.


** A maker's max dissipation spec for a semiconductor is not related to the
application.

It is only related to the device itself.

Normally, the figure given is for *ideal* operating conditions - like when
mounted on an infinite heatsink held at 20C.
