Thanks David, after reinstalling again, I have tested "Digital Surround 5.1 (HDMI) nr 4 Output" and audio does work (only after installing the nvidia proprietary driver).
It is good that a user can now configure this via the GUI. However, somehow I missed this after selecting a few options. I had no idea what "nr 4 Output" meant. Looking to get an out-of-the-box solution, what could we do about this? When I edited the alsa config to limit the available interfaces exposed to pulseaudio, the drop down box displayed:- Digital Stereo (HDMI) Output Digital Surround 5.1 (HDMI) Output Which was perfect and simple. I think the solution to this lies in alsa. Unless these other three outputs have any use, then I think alsa should not expose them. (If they do have any other use, I would be interested to know what) The question is whether it would be technically possible for alsa to know which interface is valid? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716371 Title: Nvidia HDMI - four codecs, which one is the right one? -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
