I am trying to get HDMI output using a Gainward Nvidia 210 512 MB on Ubuntu 10.04 Lucid Lynx.
I have upgraded alsa-driver, alsa-lib and alsa-utils to 1.0.24 by building from source, thanks to this blog post.
Some relevant output...
user@box:~$ lspci | grep Audio

...done.
Any help appreciated.
PS my video card is connected only through the PCI-E slot. I assume there is no extra audio connection required.
