No. audio is always decoded by mplayer and played by soundcard.
It comes from mplayer's design - audio and video are separated at demuxer
level. It's the main reason why is no audio-via-dvb support commited yet. I
have to do big design changes in both demuxer and timing (a-v sync) layer.

The quick'n'dirty way is implementing ao_dvb which passes audio to the stream
opened by vo_mpegpes, but i won't keep this code - too messy.

The main problem is that mplayer was designed for software playback. It has
its own timers, and everything is synced to the soundcard. I have to give
this up to get hardware decoders work well.
