Under openSUSE 11.1 how is it possible to use the audio output via HDMI? I see in the mixer "HDMI Audio" but no sound output is produced.
It depends on hardware.
HDMI over ATI graphic board should work with fglrx driver. IIRC, HDMI on radeonhd came after 11.1 release. On Factory, it should work.
HDMI over Intel graphic isn't supported on 11.1. On Factory, it could be, but not sure. The XOrg:Devel repo should work, though.
In general, X has to run to enable HDMI output, because the HDMI is a composed output of both graphic and audio, and the graphic driver has to cooperate with the audio part in some role.
Also, note that the way to choose HDMI output depends on the hardware implementation. In some cases, you'll have an individual HDMI output audio device, and in some cases, HDMI is bundled together with the normal analog output. That is, the hardware implementation of HDMI is very chaotic right now...
