AC3 support in the audio driver

Hi All,

I have an audio adapter driver which plays PCM data, now if I want to
support AC3 format also, is it enough if my driver creates a pin with the
AC3 format as input and then handle both PCM and AC3 by checkin the GUID
of the received subformat GUID.

Any information is helpful,

Thanx and regards,
Kedar.
