I finally got HDMI sound to work but I don't understand HOW I got it to work. I tried:
Audio Capable Device: hdmi
Passthrough Output Device: hdmi
Audio Capable Device: hdmi
Passthrough Output Device: plug:0,3
Audio Capable Device: hdmi
Passthrough Output Device: plughw:0,3
and none worked. I then enabled "Downmix Multichannel Audio to Stereo" and then it started working. The Dolby Digital and DTS logo's light up (on my reciever) depending on the source I was watching. So how exactly is "Downmix Multichannel Audio to Stereo" allowing the HDMI sound to pass to my reciever? Also, if this site wasn't available I would still be trying to get HDMI sound to pass to my reciever. So my question is how did someone come up with plughw:0,3 or hdmi or plug:0,3? I looked over the aplay -l results and didn't see any of the above so why does plughw:0,3 work and hdmi not? BTW, below is the results of my aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC662 Analog [ALC662 Analog]

I am not one to blindly just go with things and really would like to know why my sound is working now so if something similar happens in the future I know where to turn to.
