[mythtv-users] Airtunes upmix ?

[Guillaume Membré]

Hello,

First of all, kudos to all dev of mythtv !

I followed the guide http://www.mythtv.org/wiki/AirTunes/AirPlay and
setup successfully iTunes on mac OS X 10.8.2 to use my frontend as a
remote speaker to play mp3 file.
Mythfrontend is running on a atom ion itx and is connected to a 5.1 speakers.
When I play the same music in iTunes and mythmusic, I don't get the
same output :
- mythmusic : the sound is upmixed, so I get a "dual stereo" on front
and back speakers.
- airtunes : sound only on the front speakers.

Is there a way to tell the frontend to upmix the data coming from airtunes ?

Thanks a lot for your help.
