HDMI Audio issue / Strange aplay -l output

I've yet to get HDMI audio output to work correctly. I've tried the advice to use aplay -l to find my card/device number, but my output seems different from every other one I've seen online. To my knowledge, I have the proprietary NVIDIA drivers installed correctly.

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], 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

In all the examples I've seen, after the line:

card X: NVidia [HDA NVidia], device Y:

there has been additional data to allow the user to determine which device. I've tried to play audio using aplay through each device and none produce sound output. I have a Windows drive on this computer on which sound works, so it isn't a hardware issue. Anyone know how I can fix this?

Update: After some more research, I've been able to force white noise through with:

sudo speaker-test -Dhw:1,7 -c2

I can also force aplay to play a .wav file. But after multiple go's trying to configure asound.conf, I can't seem to get anything else to play.

Re: HDMI Audio issue / Strange aplay -l output

i had the same problem the device you need to use is propably 9 install alsa-utils if you havent and run alsamixer then select the Nvidia device and check if all 4 of them are unmuted (the last three will probably be muted...)
You can unmute them with M after that test the devices again with aplay

Re: HDMI Audio issue / Strange aplay -l output

Thank you for the response. Device 9 produces no sound, even speaker-test or a .wave file with aplay. And they all already were unmuted in that fashion, before I tried any of the tests.
