I am having trouble getting sound over HDMI,
HDMI is selectable as the output but not as the output device or the pass through device further down.

Solved!

Fix is in kernel
Linux 3.10.5-031005-generic #201308040618 SMP Sun Aug 4 10:19:06 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Hehe - you are a lucky man. I rewrote that wiki page yesterday night :-)
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

I can confirm that HDMI Audio on Haswell doesn't on any kernels older than 3.10.

None of the workarounds in the linked wiki page had any effect with Haswell, an upgrade to a newer kernel is the only way to make HDMI Audio work, at least for me.

Another interesting note is that, when I turned HDMI Control OFF, as suggested by that page, the HDMI output is not recognized by XBMC, but when it's turned ON it works. Also, if the AVR gets turned off and back on without rebooting the HTPC, it stops working.

Other issues:
No/distorted surround sound through PulseAudio (Ubuntu sound settings), only stereo mode works. Pass-through still works though.
Kernels >= 3.9 gets defaulted to RGB Limited colorspace (16-235). Fix with sudo xrandr --output HDMI2 --auto --set "Broadcast RGB" "Full". Has to be done after every reboot.
Loosing HDCP handshake after AVR power cycle or display mode change (sometimes).

As of right now HDMI support for Haswell i Linux seems to be very buggy, to say the least.

Just wanted to pop in and thank you guys. Been trying to get HDMI audio working for 2 days on my new Intel NUC.. this thread fixed my issue. Updating kernel to 3.10.x fixed it for me. Currently enjoying some Bob Dylan on my TV Smile
