Looks like it - thats what you get for buying cheap :(
The digital-setting in XBMC is greyed out - I cant change it. I allowed EEPROM writeback in Avalaunch which gave me the option to activate DTS/DD but still didnt work.
This really suck - the cable gives me digitally audio but since the xbox cant detect it, it wont output DTS/DD - I dont know where the xbox hides this info (bios, I presume?) but it must be possible to hack this somewhere.
(Or I could give up my daily cola and save for a real cable-pack :rolleyes: )
Thanks for your help guys.
