[RESOLVED] No Audio from Nvidia HDMI

Hi

I've recently purchased a Zotac ZBOX machine to make it as my media server machine. I have connected my ZBOX server to my A/V receiver through HDMI. Video works(not playing Blu-Ray quality properly), however I can't hear any audio from my speakers.

Here's my Nvidia card info:

03:00.0 VGA compatible controller: NVIDIA Corporation GT218 [ION] (rev a2)
03:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)

Here's aplay -l output:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I have nothing in ~/.asoundrd. I have modified /etc/asound.conf to:

defaults.pcm.card 1
defaults.pcm.device 9
defaults.ctl.card 1

I have set the device to 3, 7, 8, and 9. But when I go to alsamixer, I can only set PCM bar. S/PDIF, S/PDIF 1, S/PDIF 2 and S/PDIF 3 bars don't change, even when I press "m" to unmute them.

EDIT: I set the device to 7 and I was able to hear the audio from mplayer. Even though Alsamixer's options for S/PDIF channels were not adjustable.

I cannot see Nvidia hdmi modules in loaded modules at:

cat /proc/asound/modules 
 0 snd_hda_intel
 1 snd_hda_intel

Here's lsmod result:

# lsmod | grep '^snd' | column -t
snd_hda_codec_hdmi     29298   4
snd_hda_codec_realtek  30893   1
snd_hda_intel          35816   0
snd_hda_codec          145736  3  snd_hda_codec_realtek,snd_hda_codec_hdmi,snd_hda_intel
snd_hwdep              6364    1  snd_hda_codec
snd_pcm                76860   3  snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel
snd_page_alloc         7266    2  snd_pcm,snd_hda_intel
snd_timer              18687   1  snd_pcm
snd                    58893   7  snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_hda_codec,snd_hda_intel

If the module is not loaded, then why Nvidia is showing up in aplay -l?

I installed Debian with Gnome 3 initially. From gnome sound management window I was able to set the default audio hardware to HDA Intel and get the sound to my speakers through HDMI and my A/V Receiver. However, I cannot any sound in Arch, even when I'm using intel HDA card.

I installed Arch to maintain a very light weight OS with no desktop environment. That's why I'm using OpenBox without any fancy GUI based configuration manager.

Any thoughts on what I'm doing wrong?
