Hi guys,

I've been trying to find a good file which I can use to test my 7.1 setup in Dolby TrueHD. I can only find channel test files for 5.1 on the dolby homepage and on demolandia.net it seems that the 7.1 file has been taken down.

Does anybody know where I can find such a file to test my system with?

Thanks,
Christian

Thanks for the tip, but I am looking for a file, not a disc.

So more tips are most welcome.

Hopefully this 7.1Ch DTS-HD MA - Speaker Mapping Test File will be okay?

Thank you, but I am covered when it comes to DTS HDMA; it's Dolby TrueHD I would like to test.

Best regards,

Oh sorry, my mistake redface.gif

Hopefully this 7.1Ch Dolby TrueHD - Speaker Mapping Test File will be okay instead?

As you may or may not know. When Dolby TrueHD is muxed into the .MKV container, the Dolby Digital core is automatically removed. Which (currently) makes it impossible to mux into the .M2TS container.

No, I did not know, and frankly I don't really understand what you wrote there either. When I read about these things I find it very easy to mix up containers, formats, PCM, Dolby and all the other things.

But what I did figure out was that (according to this file you have given me) my rear speakers and my side surround speakers are switched, when I playback Dolby files on my Mac on OSX… I really need to get a media computer which can do 7.1 surround setup without hassle.

Are your speakers correctly mapped when you play the 7.1Ch DTS-HD MA speaker mapping test file?

Well, on OSX, what happens is that both the surround speaker and the back speaker is output through the surround speakers. So basically neither Dolby nor DTS HDMA really works. But if I boot the Mac to Windows, it can play both Dolby and DTS with all 7.1 channels. I am using XBMC in both cases.

Same issue/any updates?

Looks like I have the same issue with these test files.
On a MacBook Pro (MBP) connected via HDMI to my Sony receiver.
surround and rear speakers are reversed..even though all speakers map correctly in the Audio Midi Setup app..
Found that VLC renders the TrueHD clip correctly, but other programs do not..but for DTS, like with the other poster Christian, it just blends the surround and rear speakers instead of only having 1 speaker make sound at a time.

Any tips/help with troubleshooting appreciated..

I am using VideoLan Player (VLC) version 2.2.1 (the latest version, as of Aug 2015) as my test tool.

The DTS file is reported by VLC as only 5.1 (3F2R/LFE)
The Dolby TrueHD is reported by VLC as 7.1 (3F2M2R/LFE)

The Dolby comes through correctly, with 7 discrete speakers.
The DTS couples the Surround with the corresponding Rear Surround.

This could be a limitation with VLC. It's not the definitive software for determining the embedded audio encodings. But it's pretty good at playing video.

Well, I tried getting this to work on a mac with both vlc, xbmc and some other players. I ended up posting bugs for the various players, but in most cases they use third party decoders which can't handle OS X very well. Here is an example ticket from xbmc: http://trac.kodi.tv/ticket/13753 . I don't think we'll se broad support for 7.1 in a long time, since it is a small subset of users that really do have all those speakers.

So there are some limitations with the players and even more limitations with os x. In my case, I ended up buying a Dune player, which decodes all kinds of formats really well. Sorry I can't be of more help.

I have been looking for this information as I have video files that are supposedly 7.1, but VLC keeps showing them as 3F2R/LFE, which is only 5.1. I recently acquired a video that is truly 7.1 because it is being listed as 3F2M2R/LFE.

I have 2 questions:
  1. I know that 3F2R/LFE for 5.1 stands for 3 Front (Front Right, Front Center, Front Left), 2 Rear (Rear Right, Rear Left), and Low Frequency Emissions (The Subwoofer). What does the 2M in 7.1 stand for? Does it mean 2 Middle (Right Middle, Left Middle)?
  2. What does 9.1 look like?

Does you system sound card support 7.1 output?, else connect your receiver and select that as your sound card and then start VLC and check.

In my case, the test tones in the Mac MIDI Audio Devices "Configure Speakers" screen all work fine, for the entire 7.1 Rear Surround config.

But any speaker test file I've tried so far still seems to do that behavior of flipping or mixing the Surround and Rear Surround speakers.

I did notice that on the "Audio Devices" screen, the Source shows as my TV (Samsung) instead of my receiver (Sony). Not sure it's significant thought since like I said, it still sees and can send correct test tones to each of the 8 channels in my 3/4.1 config..

Let me know if you have any troubleshooting ideas! (i.e. new 7.1 test files, settings on TV, Receiver, Mac..)

Hi aravindhan,

No my system doesn't support 7.1, only 5.1. That exactly wasn't my question though. I mean it can play 7.1 files, as I did find one and the properties do list it as 3F2M2R/LFE.

My questions were:
  1. What does the M stand for in 3F2M2R/LFE? Does it stand for Middle Speakers?
  2. What does 9.1 look like. I mean my home theater system receiver can do up to 9.1, not my computer, but only have my home theater system setup for 5.1 right now. I was just curious, if I was to ever obtain a video file that was 9.1, what would the audio properties of the file look like?

These aren't issues that I am having, they are just questions I am asking out of curiosity.

Try http://thedigitaltheater.com web page. There you can find truehd,dolby atmos and dts sample files and a lot of 1080p trailers with 5.1 audio.

I am assuming you are hooking your computer up to your receiver using an HDMI cable, which your TV is also hooked up to this receiver through HDMI. If so, this is normal for your computer’s audio properties to show your TV instead of the receiver. It may also flip flop back and forth. There is a good chance that if you have your TV turned on the computer’s audio properties will show your TV, then if you turn your TV off it will show your receiver instead. May or may not be true, but regardless, it doesn’t matter. It is working correctly.

The issue with your speakers being incorrect when you run the test from your speakers is most likely that you hooked the speakers up incorrectly. The receiver would/should be able to determine the correct output signal being sent to it from the computer, especially if you are using HDMI. Have you run the speaker test through the receiver itself? In the menu on your receiver there will be a speaker test, it will check to make sure they are working and setup correctly. If the sound isn’t being outputted to the correct speaker, based on what is displayed on your TV, then you have the speakers incorrectly setup and need to adjust where you have them plugged into on the receiver.

I have a similar setup. LG TV going into a receiver using HDMI ARC (Audio Return Channel). I also have an HDMI cable hooked up from my computer into the receiver. When I run the audio test from both the receiver and the computer it works fine.

I am not sure what you are trying to do, if you are just trying to watch movies from your computer or actually play games from your computer onto the TV. If it is just watch videos, then you really don’t need to hook your computer up to your receiver, as long as your computer is on the same network as the receiver and TV. If you have a Smart TV and it supports WiFi or a network connection, you can just stream video right from the computer onto the TV using Windows Media Server. Your TV and receiver will also need to support ARC and will need it enabled on both the receiver and TV, if they are capable. Most newer equipment does support ARC and a network connection. This would be the best option to stream watch video or pictures. Also, most receivers will allow you to stream music audio from your computer to the receiver without hooking the computer to the receiver, as long as it is on the same network. So unless you are using it to play games, there almost isn’t a need to hook up the computer to the receiver, unless your receiver or TV really doesn’t support this stuff. I mean my equipment is about 2 years old now and almost all new stuff, if you buy something that has a little bit of quality in it, would come with these features. It might sound like you are using a MAC, if so, then I’m not sure if they have something similar as Windows Media Server. I would think they do because in my opinion MACs are always superior and ahead of the game over Windows, even though I never owned one, but used to use them all the time and are better quality. I have an iPhone and use airplay to stream audio from my phone to the receiver all the time.

I'm wondering this myself... Of course VLC can't play everything but that's why you use MPC-HC. That plays the True HD formats VLC won't play.


The thing is... connecting my Samsung one connect TV to HDMI is great and all but I can't seem to get DTS-HD or True Audio into the Marantz using the one connect device meaning I must either use a really long HDMI cable and connect it to my PC or buy something that can actually pass the codecs into the Marantz directly like maybe a KDlinks 400 device. Of course buying an official blu ray player is always on the table but that's no fun.


So I use PLEX to stream some movies and shows into the One Connect into the Marantz and I have noticed I really don't think it has ever used HD audio and I don't know what light on the 7012 would even light up since it's possibly never happened.
