I have the exact same problem as lintweaker.
I have a new 2010 mac mini (MCP89 / Geforce 320M) and I can't get any sound through HDMI in Ubuntu.
None of the /proc/asound/eld#?.0 lists a connected device.
Should I start a new thread or is it OK to post here?
I really hope that you can help me, as I have used a lot of days on this and I don't want to give up
I'm using Ubuntu 10.04.1 LTS Lucid.
Latest nvidia 256.44 drivers.
I have installed the latest Alsa snapshot from here the link from the last post:
But, when I look in the patch_hdmi.c file from the snapshot, I can't see the patch code that Stephen Warren posted, i don't get it?
