Benchmark DAC1 does not decode DTS/Dolby Digital signals. And Benchmark DAC1 does not have digital output. It only has analog output. In order to test to see Benchmark DAC1 outputs a bit perfect digital output, you need to open up the case and do some mucking around with the internal components.
How is your setup hooked up?
That wave file is still a DTS encoded file. You need a DTS decoder to decode that file. This can only be done in the following ways,
1) Your software player
2) Your software player outputs the digital signal to an external DTS decoder (such as your receiver)
Because the Benchmark DAC1 does not have a DTS decoder, all you hear is pink noise.
And because Benchmark DAC1 does not have a digital output (pass through), you cannot hook up your DTS decoder to the Benchmark DAC1 to test to see if the bit perfect digital output is extracted from the USB port.
