I have used a HDMI cable to connect my LCD (which is connected with my speakers) with my Nvidia 275 GTX graphics card. I can not get the sound output to work. The hardware itself is working probably - I tested it under Windows.

Currently I am running Kubuntu 9.10 64 with Nvidia 190.53. The sound output worked fine before I installed the HDMI connection.

(German output - I can change it, if you tell me how :))

I think I am missing the something-hdmi module? Is there such a thing?

Edit 2:

I have updated alsa.

Output of cat /proc/asound/version:

HDMI audo still does not work.
