I did not realize my patch was buggy, I had a white line and because of it the last part of the patch did not get applied. Now aplay -l is fine, and I can use the hdmi again, but still it defaults to stereo. With a "default" asound.conf speaker-test won't allow for more than -c2. I tried to add channels 6 in the conf file, but it made no difference... I will try your other suggestion.
