There is a simple trick to find out if an audio transmission is bitperfect. Bitperfect is a must if AC3/DTS signals are sent.Not sure, if doesn't say, probably not.
All one need is a special audio file and a home theater receiver with AC3/DTS decoders on board and coax/optical input - even the cheapest one can do this.
I made myself an audio file (click) - it is an ordinary *.wave with encoded AC3 data inside (hidden information). If the device is bitperfect (signal pass through) and all the data transmission is bitperfect as well, a hidden information will be decoded properly by the home theater receiver - music playing. If transmission will be altered in any way, the HT receiver will not be able to decode it so a static noise will be heard.
Of course, no DSP in chain, wasapi exclusive or ASIO and no software volume control (all the faders to max - 0dB).
So if anyone would be so kind to make a test I will be very appreciated.
