[Stigmata]

Hi all, I'm using r29717 on a 21.5"/9400M iMac and I'm using digital audio output to a DIY stereo amplifier with dac. The amp itself it's ok, but I have a strange problem with XBMC playing movies with DTS audio: the audio is unbalanced, I hear dialogues coming 80% from the right channel.
Dolby Digital movies are ok, only DTS has problems.

What can I do?

Thank you!
Francesco
