audiomixer: only passthrough on dynamic data

Browse source 
When the dynamic data flag is set on the buffer data, it means the
consumer can deal with any data pointer set on the buffer and we can
simply pass the one from upstream to downstream. If the flag is not set,
we need to copy the buffer data.

See #5009
