Hello Clemens,
First of all, many thanks for your great job with the DD for CMI8788.
I performed some tests with your last bete-version of it and would like to send you a short report:

Test environment:

CMI8788 card: Bgears b-Enspirer connected over a TOS-link on DD 5.1 receiver.
OS: Debian Leny (testing)
Kernel: self built on base of 2.6.23 (from distribution), configured without ALSA

ALSA (user land) from Debian distribution:
alsa-base 1.0.15-2
alsa-utils 1.0.15-1

ALSA driver: your beta code (./configure (no params), make, make install)
I took also your CMI8788.conf and aliases.conf into /usr/share/alsa/cards

In all tests, NO surround, but only stereo sound was working, i.e only "Front Left" and "Front Right" were working ;-(
Test with (plug:)surround51 and 6 channels failed. 
Please have a look at printouts below.

I am not really an ALSA-expert, so sorry if the half-successful results came through any missing configurations.

Please let me know if you need more information or have any suggestions.
I would perform additional tests with pleasure, thus please let me know if any additional tests would be useful.

Best regards,
Tomasz
