Hey guys... just replaced my dahrma XBMC installation with a fresh install of XBMCubuntu and I don't have any audio over my ION2 HDMI.

I think that my main problem is that ALSA isn't seeing the HDMI portion of my NVidia card.

aplay -l

Code:

**** List of PLAYBACK Hardware Devices ****

  Subdevice #0: subdevice #0

aplay -L

any ideas?
I've upgraded to the latest nvidia drivers and have downloaded and compiled ALSA version 1.25 with no luck.

Try setting your audio output device and audio passthrough device to custom and enter in plughw:1,3 for the device.

no dice. Failed to initialize audio device.

All mixer channels are unmuted.

I'm still troubled as to why aplay -l is reporting HDMI 0 [HDMI 0]. That seems abnormal.

Im running into the same problem with my Lenovo Q110 - it's showing HDMI 0 and I've tried "plughw:0,3" without any luck.

[Zxurian]

had the same problem with mine, this worked for me

with beta3 I had audio problems too. Try this custom setting

Code:

alsa:hdmi:CARD=NVidia

P.S. remember to unmute nvidia output with

Code:

alsamixer -c <card_number>

[tocheeba]

I do that with my Q110 and I get a bunch of clicking sounds when playing video.

That didn't fix it. Still cannot initialize audio device.

I've been watching this thread with interest to see if any solutions pop up that could help with my own issue with no sound over HDMI on my Lenovo Q150... Any movement?

[tehtide]

I'm still fighting it. I got it to work with the plughw:1,3 custom output device. However I'm still not 100% convinced that there isn't another problem somewhere.

I was having same issue, also have an ION2

Post #15 here worked for me
http://forum.xbmc.org/showthread.php?tid=126757&page=2

I put "hdmi:CARD=NVidia,DEV=0" for both custom inputs and voila

You may also have to go to console and run alsamixer and unmute.

Hope it works for you
