If you check the logs with -v audio, you'll find that some audio
processing is occurring making myth having to first decode the signal;
 either resampling, software volume, conversion of format, up mixing,
down mixing etc.

As explained earlier; as re-encoding to AC3 doesnt add anything (to
the contrary) the if audio stream has to be decoded first, and your PC
supports the number of PCM channels required for playback ; then
that's what it uses.

It will sound identical.
