 on the front edge (user-facing), i'd say yes.

 you have to think: is it just going to get routed through the device
and out the other side, in which case you've just wasted N lines, or
is it going to some built-in speakers, in which case you _still_ don't
want to put it on the connector because a simple USB audio driver IC
or even an STM32F with a Class D (PWM) amplifier on the back would do
the same job.
