[Solved] HDMI audio broken after upgrading to kernel 3.13.4

Hi,

Yesterday I upgraded to kernel 3.13.4 from 3.12.9 and
HDMI audio through my nVidia GTX660 card stopped working.
The problem occurs both with nouveau and nVidia drivers.
My system is an aged Intel quadcore Q9400 on a Intel motherboard.
By typing "aplay -l" I get:

card 0: Intel [HDA Intel], device 0: 92HD73E1X5 Analog [92HD73E1X5 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: 92HD73E1X5 Digital [92HD73E1X5 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Strangely the alsa card number changed from 1 to 2
after the kernel upgrade.

I would really appreciate any help.

Thanks

Re: [Solved] HDMI audio broken after upgrading to kernel 3.13.4

setting the load order of sound kernel module:
sudo vim /etc/modprobe.d/alsa-base.conf

edit ~/.asoundrc to specific the default device, modify your setting, like this
defaults.pcm.card 2
defaults.pcm.device 0
defaults.ctl.card 2

Thank you very much, silenceleaf.

I managed to make it work with some tweaking like you said.
But only after a deep power cycle, unpluging any power to the system.
Just turning off the machine's power button was not enough. Odd!
