Can anyone suggest a couple of ALSA-safe cards that
will provide "bit perfect" SPDIF throughput ?
In other words, if I play back a 44.1khtz CD that the
card will not resample the signal, at all, on the way
through to the SPDIF output.
And, in the case of a nVidia MCP67 (hda_intel), which
seems like it does 96k and 192k, is there some way I
can determine how well, or not, it passes through any
digital signal?

Any card with a CMI8738 or CMI8768 chip. The analog quality,
especially that of the 8738, is lousy, but they can do bit-
perfect playback and capture of digital data.

If that includes CMI8738-MC6 you can get it on e.g. a Terratec Aureon
5.1 PCI for approximately 20€. It works well for SPDIF out here, haven't
tried input.
