Linux [SOLVED] HDMI audio works on PC, but not through XBMC

Does aplay -l show The NVidia device as card 1 rather than card 0? If so, try disabling the onboard sound in the BIOS, then using the following settings in XBMC:

Audio Type: HDMI
Speaker Config: Your speaker config
DTS and AC3: Yes
Audio Device: (if this is already working for music and whatnot over HDMI, don't change it)
Passthrough Audio Device: custom
Custom Passthrough Device: hdmi:CARD=NVidia,DEV=0

If that doesn't work, change the "0" to 1, 2, and 3 until it does. If none of them work, you could try the direct-to-hardware devices: hw:CARD=NVidia,DEV=3, hw:CARD=NVidia,DEV=7, hw:CARD=NVidia,DEV=8, or hw:CARD=NVidia,DEV=9.

Just to give an update, I never got this to work properly. I tried every combination, I'll have to assume the fault lies elsewhere than just with XBMC, perhaps my receiver is not accepting the bitstreaming over hdmi, who knows. I've decided I'll be happy enough with it as surround "analog" over hdmi, since my main need was to get everything going over a single cable so I can ceiling mount the projector.

If anyone finds themselves in this position, this guide seemed pretty thorough, and got me about as close as I've gotten yet to digital passthrough, though the end result for me was screeching sounds and the video running at over twice the correct framerate, for reasons unknown to me... http://imadethisdesign.blogspot.com/2012...whdmi.html

For now, I'm on to my next new big problem. On two 64-bit 12.04 computers in a row playback of DVD file has been unusably jerky, while HD files have been perfectly fine... Who knows... This worked without issue for me on older versions, not sure why it would break now...

Check volume levels and that the channels are not muted (using alsamixer).
I ditched HDMI audio long ago; using optical output only.

i have a related issue - i have hdmi video and audio when using VLC player in XBMC desktop but not through Media center.
even using the same audio settings in VLC as in Media Center.

Optical isn't really an option in this case as my receiver needs an update to allow for assignable inputs and it doesn't have usb, so it needs to be done digitally over optical out from a burned audio/firmware CD... so yeah...

Vidro3, when you say Media Center, are you talking about Windows stuff

no, i mean XBMC media center as opposed to the Desktop in XBMCBuntu

vidro3, so, you have no hdmi audio whatsoever in XBMC, or just no digital passthrough audio?

To all: I know it is unrelated to this topic, but if anyone knows anything about my DVD issue, I'd love to hear it.

You may need to remove pulse as only the bleeding-edge versions have passthrough support.
