Hejsa... Jeg havde en længere support "samtale" med creative da jeg havde (har) et problem der ligner dit og jeg fik denne mail fra dem:
Dear Daniel
Thanks for the email!
It is possible to get multi-channel audio throught digital out when
playing back ac-3/DVD movies. But for games, I'm afraid you would need
analog connections or our The DIN connection (not the coax to din
connection, din to din) for it to work. Coaxial and optical connection
can only carry a stereo signal, the speakers test and EAX positional
audio needs 3 stereo channels to work with 5.1. The DIN connection(not
the coaz to din) can do this and that is why that works.
I hope I have answered your enquiry. Thank you.
Please retain all the previous correspondence when replying to this
email.
Best Regards
Andy Teyu
