Hello, (since I did not get any feedback on the user ml, I'm trying it here, sorry...) I am using the HDMI output of my radeonhd 4670 to get sound, but I cannot get ALSA to work with (5.1) multichannel, it only outputs to the front left and right speakers (checked by speaker-test). I tried following this howto: http://www.cse.ohio-state.edu/~bondhugu/alsamch.shtml but it did not do much for me... and whenever I tried to add slave.channels 6, I just could not use alsa anymore, it always complained about this line... I tried channels 6 as part of the slave.pcm{} too and got the same result... What should I look into? I tried with 2.6.32 and alsa-lib 1.0.21.a, and then 2.6.33-rc3 (stil using alsa-driver 1.0.21 it seems) and alsa-lib 1.0.22 and no success. I am using the radeonhd xorg driver to get HDMI audio. I compiled alsa-driver 1.0.22.1 on top of a 2.6.32.2 kernel and the result is still the same although this time I did not play with the asound.conf file. Pulse audio on top of alsa does give me a 5.0 setup or at least I can hear that from the speaker-test.
