How do I test that Kernel Streaming or ASIO is playing bit-perfect audio?
Using a CD-Audio format DTS track (16-bit, 44.1khz) is the most effective way to test for true bit-perfect playback. If anything happens to corrupt/modify/resample your audio, it will destroy a DTS-CD track.
This can only really be tested with SPDIF out to a DTS-decoder of some sort. The theory is that your computer will treat the track as regular CD-Audio PCM and pass it out to your reciever, but your reciever will see that the incoming stream is DTS and decode it appropriately. Links to DTS-CD samples will come later.
