Hi all,

 I have installed a centos 6.2 x86_64 box to use as a multimedia center.
All works ok, except sound over hdmi using nvidia graphics card. My lspci
output:

Under gnome control panel, all seems ok: under sound preferences, sound
output is configured to use HDMI channel.

I am using nvidia drivers from elrepo.org (nvidia-x11-drv-290.10
and kmod-nvidia-290.10). Somebody knows where can I find some doc to
resolve this? Any idea?

Thanks
