[QUOTE="edterbak, post: 324746, member: 69192"] Well.. I think there might be something else going here. your receiver can receive probably AC3 + DTS in 44.1 and 48khz (probably also 32/96khz). The soundcard of the PC is theoretically capable of sending 44.1/48khz audio signals. But the thing is with the standard drivers the output signal is fixed on 48khz.
