Hello. I've recently upgraded to the latest build of Gotham and its looking really nice.. apart from the fact that I cant passthrough DTS HD MA.

In Audio output settings it wont give me the option (on either normal, advaced or expert) for DTS HD MA. Only DTS etc.

What's wrong?

When I play a HDTrack with DTS-HD MA it shows up as PCM on my display and it wont light the TRUE-HD lamp.

Please help!

Best regards.

Hey,

do you use pulseaudio?

I had a (let's say so) "discussion" in the past, here's the thread:
http://forum.xbmc.org/showthread.php?tid=185768

short story:
No DTSHD or TrueHD bitstreaming support in pulseaudio, maybe it won't come at any time since the devs don't think it is useful

FernetMenta Wrote:Because there is absolutely no advantage in bitstreaming HD audio on a machine which has enough power to decode.

Quote:PulseAudio does not currently allow TrueHD or DTS-MA passthrough, this is a PulseAudio limitation and not a limitation of the XBMC implementation.

Ni dit, I do not use pulseaudio. Not What I'm aware of at least. I have only installed Gotham and my skin. and i want to play dts hd movies.

Ok, so this isn't your daily-desktop-PC but a standalone HTPC only for xbmc?
windows or linux?

I depends on if you want to play 2 sounds from different sources at the same time (like browser or any other progran on your PC which uses sound) then you need pulseaudio -> no DTSHD or TrueHD bitstreaming.

If you use it only as HTPC and XBMC is the only program which should play sound, you could stick by ALSA (or whatever the windows-pendant is called)

This is my daily PC and I only use xbmc. I use windows. I upgraded to Gotham last night and the option to pass through dts hd etc went missing. I'm unsure about what to do

tausche · 2014-03-22, 13:35

I installed the windows-version Gotham beta 2 now on my win-PC for testing,
if setting the "settings level" to expert, the bistream options show up, but also only DTS and DD, no TrueHD or DTSHD.

doesn't matter if I choose "directsound" or the "WASAPI" output over HDMI...

seems to me it is still not supported?
sorry, maybe some other will know more...

Yeah, that's exactly the problem.

did you set speakers to at least 5.1? And you must use WASAPI

if it still fails: Debug Log

Yes sir, it's 5.1 and I use wasapi, and I'm still unable to get the option to passthrough, just like tausche

FernetMenta · 2014-03-22, 14:13

If you don't see the option, your audio device reports that it does not support it. A debug log could give confirmation.

Borked · 2014-03-22, 14:21

Ah ok, how do I go about posting the debug logg? I've got a Yamaha rx-v771 so it deffo supports it. And afaik I had the option to select it with frodo.

FernetMenta · 2014-03-22, 14:30

wsnipex posted a link for debug logs.

Also good reading. Section 3. XBMC is aware of those formats

I mean how do I go about "reproducing" the problem. It just an option that's not there. I'll read thru the articles when i get home.

tausche · (This post was last modified: 2014-03-22, 14:42 by tausche.)

The "reproducing" in your (our) case is the xbmc-restart.

XBMC will search and initialize soundcard, videocard, etc. when starting up, so the best is to enable debug log, restart XBMC and the log will probably show errors when initializing the sound device.

I think the easy one will do
