ac3 and xmbc

[topher]

I have a foxconn nt330i running xbmc connected via hdmi to a onkyo 605 amp, when playing movies in ac3 there is always audio missing, I guess this is because the onkyo doesn't support ac3..

Is it possible to get xbmc to do ac3 via lpcm?

cheers

AC3 is just another name for Dolby Digital which the amp will support.

If you go into the XBMC system options, and then audio, you'll have some entries to tell XBMC how many speakers you have, and whether your amp can use AC3/DD, try unticking which should decode to PCM, and then see what happens.
As long as your amp supports audio via HDMI DD shouldnt be an issue.

DD+ works fine with XBMC and my amp. I'm on Dharma betas atm.
If you're on a linux build it could be some conflict there.

Does your amp support on-board DD decoding ? If so, then go to System Settings -> Audio -> and set the option for DD (and DTS if it does that). If not, then you'll either get the track over multichannel LPCM (if your amp and hdmi output support it) or downmixed to stereo.

FYI - there's some nvidia drivers on which multichannel LPCM is broken, if you're using a nvidia chipset.
