Ok, and here is the rub: playback is not perfect, and neither seems
to be the sampling. Probably at times error interpolation sets in,
probably at times samples get lost or replicated. Not much, perhaps
once per minute or so. This leads to audible clicks, of course.
You're assuming a flawed spdif stream and, well, people keep suggesting
changing the spdif cable. It's supposed to have an effect on stream
quality worth mentioning. Don't know myself.
But try setting the c-media card to respect the incoming spdif clock.
That should make a difference.
