Thanks!

the ONLY thing that worked for TrueHD is hdmi:CARD=NVidia,DEV=3...

Is it normal that hw:0,9 would have worked fine in EDEN (and all previous versions I've used for years) and now this comes up?

I have a Geforce GT520 card that's work with AE.
Both Output Audio Device and Output Audio are set to hdmi:CARD=NVidia,DEV=3. The same as used by cdhesse.
With the AE build from 14/4 on a Ubutu 12.04 beta release I am able to play videos these audio streams:
DTS
DTS/24
Dolby 5.1
Dolby True HD
PCM 2.0 plays with distortions
with DTS Master Audio the video looks fine, but there is no sound.
On a Harman Kardon 355 Reciever with 5.1 speaker configuration.

The computer has also another audio card with a C-Media 8768 chipset connected to a Yamaha reciever over SPDIF and in this case a 2.0 speaker configuration.
With Audio Output set to Optical/Coax and Audio Output Device set to C-Media CMI8768 iec958, I am able to play videos with these audio tracks:
DTS
DTS 96/24
Dolby 5.1
Dolby True HD that plays Dolby Digital
DTS HD Master Audio, that plays DTS
with PCM 2.0 the video looks OK, but there is no sound.

It is hard to know if my problems depend on wrong configurations or AE, as there are no information available, as far as i know, about how to configure a system to support AE.

You are going to need to take an XBMC log when trying to play PCM 2.0 or DTSMA via HDMI.

On the SPDIF connection, this type of connection does not have the required bandwidth to play TrueHD, DTSMA, or other HD audio codecs. Thus, the best you are going to get from a connection like that is DTS, Dolby 5.1, etc.

Hi,
compiled today your latest version.
Ubuntu server 11.04
NVidia GT430
custom: hdmi:CARD=NVidia,DEV=3

Cannot get audio to work properly.
With an old verison of your code (January) it worked perfectly.

Now it goes very slowly and says that "Audio device failed to initialize".

Here is my debug log: XBMC.log

thanks

The NVidia driver you're using 295.xx is a pita - try dropping to 290 or 280/285. I don't know if this is something Gnif et al can fix - that driver has caused various issues for peeps as far as I know, not just audio wise.

EDIT: for my atrocious grammar!

Does your card work properly with something like mplayer? A good test is seeing if you can play a simple MP3.

I'm running 295.40 just fine.

From inside XBMC I cannot play anything.
I was able to play with the same configuration and settings with an earlier version of GNIF.

But speaker-test works.

I might try to downgrade the driver and see if this works.

Really? I've tried numerous times now on my system (even fresh install) it fails miserably every time. That is to say it often works initially with sound on the GUI - but the moment it switches to passthrough (I guess) it fails with the same "failed to open audio device" error. The 290 and below drivers work fine for me. I've also seen Fernetmenta (iirc) report problems with the 295 driver series and his suggestion was to back off to 285 - admittedly that was video rather than audio related as I recall.

EDIT: http://pastebin.com/1DgH6mva is the log for the 295.40 driver / Nvidia G210

Ok. In my experience mplayer is a better test of if your audio is working than the in-built ALSA tools. My guess is you have ALSA issues. The other option is your DEV setting is wrong (ie mine is DEV=1 but a lot of other people use DEV=3).

Perhaps it is something in Ubuntu. I run a Gentoo system. It could also be something in your asound.conf (do you have one?)

I am using Nvidia driver 295.40 in Ubuntu 12.04 beta and that works. I am however not able to play all formats.
I compiled a new version yesterday and played some videos.
DTS HD Master audio does not play, but DTS HD High Defenition plays fine and the reciever shows DTS HD Master Audio.
If I change the audio settings in XBMC to just LPCM, videos with DTS HD Master Audio will play the DTS track.
