Hi I installed a pci e auroen terratec card into a 64 bit windows 7 pc. as was instructed by tech support I installed all the software and selected 7.1 .
Plugged it all up and selected in Myriad audio settings chose terratec 7.1 s
I noticed that it was unable to differentiate any of the channels i.e rear surround front which would provide Myriad with the 4 playlines hence when i came to try it out only playline 1 would work but mixed in with playline 2 . I then tested the audio card and the 7.1 test proved that all the channels worked correctly and independently hence I think that the Aureon Terratec is not suitable for Myriad use.  Please before I send it back does anyone have any last minute ideas as to why all 4 channels cant be recognised . Thanks Dave.
