Cannot get HDMI audio working
I'm trying to get audio over HDMI working on my freshly-installed system. I'm just using ALSA for now, might switch to pulseaudio in the future but do not have pulseaudio installed. I have onboard sound on my motherboard (Gigabyte 990FXA-UD3) and also a second video card (Radeon 7770) that also have audio outs but I'm trying to get the NVidia 960 HDMI out working

Re: Cannot get HDMI audio working
Just use pulseaudio with pavucontrol. From there you can just choose your desired output. Don't even bother messing with alsa.

Re: Cannot get HDMI audio working
I've always had great results with PulseAudio. As said, I second using that - just remember to install pulseaudio-alsa so your legacy ALSA applications get routed properly through pulse.

Re: Cannot get HDMI audio working
While I second the notion on pulse, what makes you sure that 1,3 is the correct output? It could be 1,3 1,7 1,8 or 1,9 depending on which output port you plug your HDMI in, ALSA is not going to figure that out for you automatically (which is why people suggest to use pulse, because it does do that with varying degrees of success, but it attempts to make the correct choice at least) , so try that as well. (And all of your outputs are muted, they should read 00 instead of MM in alsamixer, so make sure you do that as well)

Re: Cannot get HDMI audio working
What V1del said.
Back when I used to use ALSA, this was exactly the reason (I had difficulties outputting from my NVidia card via HDMI) - there was no way to tell which output it actually is.
I also want to say that I used to hate pulseaudio, but that was because it used to be an infant. Now it has matured and is a lot more solid, with way more software support 
(some quarries I have with pulseaudio are certain MIDI soft synthesizers and MT32 emulation, but that's about it)
