[SOLVED] Audio over HDMI stopped working? (Intel/i915)

My audio over HDMI was working fine until recently and I can't figure out what's stopped it from working... My configs haven't changed and aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav gives no errors, but no sound can be heard. There are no errors/messages in dmesg either.

My graphics card uses the Intel i915 chipset (Asus laptop).

Config stuff:

/etc/asound.conf:

pcm.!default {
  type hw
  card 0
  device 3
}

ctl.!default {
    type hw           
    card 0
    device 3
}

aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: CONEXANT Analog [CONEXANT Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Any ideas?

Just in case, have you checked the volume levels? After update to linux 3.7 my mic input was set to 0 and I had to reset it…

Yeah I checked and everything is fine... this is really weird!

I've tested audio over HDMI on windows, so I know it's not the cable/HDMI port. I've looked through my pacman.log (I tend to update daily) and the only thing I can see which could affect it is a kernel update and intel-dri. I tried downgrading those and re-tested, to no avail.

I also installed pulseaudio and pulseaudio-alsa before it stopped working. This could have broken it, but I've since uninstalled them and replaced /etc/asound.conf with my original, so that rules those out; unless there is something else that pulse could have broken?

Cheers
