That was almost the main goal of this project ....
There is an alternative option not mentioned much but you could get a sound card which supports DTS Connect or DD Live. Those sound cards re-encode multi-channel LPCM as DD or DTS connect. I used one (it was a sound card with DTS Connect) when I had a GTS250 in my HTPC. I wasn't to fond of it as you had to always select what kind of audio source you wanted to use manually (it didn't automatically detect and select). On top of that, I don't believe all games are compatible with it. Sorry I couldn't be more help.

BTW, you would most likely get the same results if you connected a standalone DVD player to your TV and ran a spdif cable to your receiver.

Its a basic limitation of most modern TVs as far as I know, in that it tells the source device(whether its a HTPC/xbox/ps3/bluray,etc) through the EDID handshake that it only has 2 channels, even though it can actually pass a DD5.1 or DTS5.1 signal to the AVR through the optical cable, evidenced by the fact that if I watch a TV programme with DD5.1 on it, it'll pass it to the AVR fine. I used to have a TV from 2006 that passed these signals through no problem, but I think there was some rule passed since then which made it so that most TVs couldn't do it anymore...

From reading all these EDID threads though, by overriding the EDID that it reports, so that it will take the DD5.1 signal and pass it through. I think quite a few people have posted setups similar to mine where they want the TV to just passthrough the surround sound signal to their AVR via optical, and seems like the EDID override is the way they did it.

PS. I currently have the HTPC outputting sound separately to my AVR via 3 analog cables, so I can get the signal ok as it is, I just want to try and get it passed through the TV if possible, so I don't have to keep switching the input on the AVR to match the source. I'd rather keep the AVR source set to the TV(connected via optical), and let everything going through the TV passthrough the appropriate signal to the AVR without me having to switch inputs on the AVR.

Based on what I've read on the threads on this forum on EDID overriding, etc.., I think I need a EDID override to accomplish this, ie. to fool the HTPC to pass the full audio signal through HDMI to the TV, and for the TV to pass-through the signal to my AVR.

I played with a few of the override files you have in your signature, and couldn't get it to override the 2 channel stereo limitation that the TV was giving out(used Moninfo to check what was being reported), and I don't see DD or DTS listed in the supported formats. After some further investigation, I *THINK* its because I'm using the onboard Intel graphics to push the audio/video signal out through HDMI and Intel IGPs can't be overridden? Is that correct?

If that's so, will a Gefen HDMI Detective Plus help me?

Thanks for your help!

i'm not sure why you connected all of this backwards...? Why not just do the following:

HTPC via HDMI > AVR via HDMI > TV?

I would think the only time you'd want to pass audio from the TV to an AVR is when
* You're watching through the TV's internal ATSC/QAM tuner
* Or if you use any of the TV's smartTV apps.

But this doesn't seems like the case you presented above...

.

Simple. My AVR doesn't have HDMI inputs... but it does have optical inputs. Its basic, but it works, I'm just trying to streamline its operation so that whenever I switch the input source on TV(from DTV to HDMI1, HDMI2, etc..), I don't have to also switch the input source on the AVR.... I want to make the TV the switcher, so I want all my source devices connected to the TV via HDMI, and for the TV to output the sound to the AVR via spdif. Am just after simple DD5.1 or DTS5.1 from the TV, nothing fancy.

Try the attached mod. It will give you 2LPCM (uncompressed audio) and muiltichannel DD/DTS capability. Of course the application must be set up to encode a multichanel DD/DTS audio stream. If the app is a game a real-time encoding audio card is required.

Thanks Tulli. I'll give it a shot.

Not sure if you noticed it in my original post, but will this work if I'm using the onboard Intel graphics adapter to output via HDMI? I see references here and there on the forums which hint that the Intel IGP won't accept overrides.

Ouch! No, it won't work with Intel IGPs.

OTOH a Gefen Detective is a more expensive solution that a AMD or Nvidia discrete card. But if the base application is gaming just get a real-time DD (or DTS) audio card. Last time I checked they were about $25.

Last time I checked they were about $25. Of course for best audio sync a discrete card with HDMI through the TV woukd be the way to go (+ the EDID Override).

Ah, thought that might be a problem...damn Intel IGP. I had thought about just getting another video card, but the issue is that the HTPC I've got is an ASROCK Core100HT, and there's simply no space for a discrete video card in the chassis. Its fine for what it does, which is just a low-power HTPC which I use to play movie/tv shows here and there, so definitely not gaming on it.

Thats why I thought maybe the Gefen detective might work, to fake out the EDID that way. I'm assuming that I'll have to use one of the existing predefined EDIDs that come with it, as I have no real way of "recording" a suitable EDID for it.

An S/PDIF connection to the AVR should do then.

Oh it works, I've tried connecting the audio from my HTPC to my AVR via both SPDIF and 3 analog audio cables to the AVR, and they both work fine to get Surround Sound.

Like i said previously to other posters, I'm just trying to streamline my setup so that I don't have to switch inputs on the AVR every time I switch inputs on the TV so that it matches eg. every time I want to switch from watching TV to watching HTPC, I have to 1) switch input on TV to HDMI1, and then 2) Switch input on AVR to Optical2(what the HTPC is connected to)..

I just want to be able to 1) switch input on TV to HDMI1, which will then automatically output the matching audio signal(which its getting from the HDMI connection) to the AVR, without having to switch to the right optical input on the AVR

Thanks for your help anyway, I think I'll give the gefen a try and see what I get with it if I fake the EDID that way.

That should work. And BTW thanks to Ryan L and shpitz. I just didn't read your posts and you had already addressed the whole problem.

Just because it will spit out bit streamed audio (DTS & DD) from a TV program doesn't mean it will "pass it through". Break out the owner's manual and I bet it spells this out clear as day. No EDID override will overcome the limitation of your TV. It will say something alone the lines of "Optical out supports DD and/or DTS through on board tuner only". You could get a smart programmable remote that switches inputs on your Logitech when you switch inputs on your TV, but personally I wouldn't waste any $ on anything else other than a receiver since you can get one of those for practically the same price as a receiver. I've seen plenty of good deals on them lately, some even as low as $100. Just check out slickdeals.net forums, set up an account, and then put "receiver" in as one of your deal alerts.

You don't have SPDIF (optical or coaxial) in the back of the PC?

There's a solution to that: Logitech Harmony One smile.gif

You tell it for each activity which inputs to select in each device, so once you select that activity (watching TV, DVD, Gaming, HTPC, etc...) it does all the switching for you.

You can also configure it to turn off devices not used for certain activity, e.g. if you selected DVD, then selected TV, you can tell the remote to turn off the DVD player before switching to TV.

Makes it simple for the wife and young kids smile.gif

Interesting point I never thought about... I wonder if the audio gets re-compressed every time it passes a device? i.e. one device creates the DD/DTS stream via SPDIF, outputs it, then the 2nd device takes that bitstream and recreates the DD/DTS stream vs. just passes it through untouched...
post #3766 of 3908
Hello,

I came across this thread while trying the troubleshoot the following problem, and could use some advice/help, please.

Background/Setup:
I have an HTPC (A75M-ITX) outputting audio via HDMI to my Panasonic TCP55UT50, which then outputs the audio via optical to my soundbar (Sony HT-CT260H).

Problem:
I ran into problems playing video files with encoded audio on XBMC. (No problems when I turn off Dolby/DTS support.) I believe I have narrowed down the problem to the fact that my "AMD High Definition Audio Device" does not show any supported encoded formats.
If I'm not mistaken, I have the same problem as described by Asmodean88 in Post #2931, which was fixed by this EDID override. (http://www.avsforum.com/t/1227161/edid-overrides-to-solve-bitstreaming-issues-for-ati-5xxxs/2910#post_21564267)

This xbmc wiki article also made me think EDID might be my problem: http://wiki.xbmc.org/index.php?title=Windows_Settings_for_AudioEngine#Configure_Windows_Sound_Settings
(I can't seem to find an updated driver for my motherboard/audio. The latest on the ASRock website is from 2011... (I installed the AMD all-in-1, as well as the Realtek high definition audio driver.) http://www.asrock.com/mb/download.asp?Model=A75M-ITX&o=All

As a final note, if I output via optical directly from my HTPC to the soundbar, it seems to be outputting both Dolby and DTS without a problem. Ideally I would like this to be the case through my TV as well, since I have other inputs through my TV that I would like to pass to the soundbar.

My questions:
1. Judging by my (albeit brief) description, will this EDID override help me? I can of course provide more detail.
2. If so, how do I go about implementing it for my setup? (I am reasonably tech-savvy, but I must say I am intimidated by the instructions in Post #1!


(Edited to add wiki article, ASRock driver info, final note, and formatting)

An EDID override will do. Capture and post the real-time EDID of your TV (see instructions in 1st.post). You could also search through the thread for an EDID Overrirde for a similar Panasonic TV model.

EDIT:

Try the attached EDID Override. Should work with your TV.

Thanks for such a quick reply.
When I have a good chunk of spare time, I will try capturing the real-time EDID, and then try installing this fix. Will report back soon!
post #3769 of 3908

hi everyone, i'm new to this forum.

I've found this thread over google searching an edid for my configuration but it seems like nobody has a yamaha avr and a panasonic et5 tv so i've searched some advices to build a customized EDID override...

after dozen attempts and hours of headache finally I got it, thanks to some kind of a guide found here ( tulli you are my personal hero )

 

my config:

 

HTPC (amd apu + amd r9 270x) -----> AVR ( yamaha rx-v571 ) -----> HDMI SPLITTER 1:2 -----> 1080p 3D TV ( panasonic tx-l32et5 )

                                                                                                                                 -----> 1080p VPR ( epson eh-tw3200 )

 

issues found in this config:

- sometimes windows ( 7 and 8.1 with latest catalyst ) changes audio output (HDMI) to 2 channels and no more recognizes all 8 channels (can't read my avr's extension edid?)

- windows 8.1 doesn't show 3d capabilities for my 3dtv (due to non-3d projector?)

- some video flashes and flicker while switching tv & vpr

 

i took audio & speaker allocation blocks from avr's cea extended edid and merged with the tv's one, overwriting its own audio data blocks...i also had to erase 2 detailed timing from tv edid ( 1920x540 both ). modified byte 02 and checksums.

installed and it seems to work....

 

here the *.inf, hope it'll be somehow useful to someone...

Yes, use the mod for the TC-P55VT30 (EDIDs are "identical"). "SPDIF" refers to the typical formats for this bandwidth (2LPCM, and multichannel DD and DTS). For more info see 1st. post.

Okay thanks again for such a quick reply.
Here's another silly question: Do I need to rename the inf file to reflect my TV model?
post #3773 of 3908

Just replace the 'HKR,EDID_OVERRIDE,"1", ...' line from your TV .inf with the corresponding one from the mod, save and use this .inf to override.

Hi,
So the override seems to work to some degree, but I am still running into problems with playback of DTS.

The override has been successful in the sense that now, under my audio device properties, DTS and Dolby are listed as supported encoded formats.

However, I still can not playback DTS audio passing through my TV to my soundbar. As a reminder, what I am trying to do is passthrough from HTPC via TV to soundbar (using XBMC as player).

Here is what works:
- I am able to output DTS and Dolby directly from my HTPC to the soundbar. (when soundbar directly connected to HTPC) (Therefore, I do not think it is a problem with my soundbar)
- I am able to output LPCM passing through my TV to soundbar. (with passthrough setup as described above) (Therefore, I am able to passthrough audio)
- I am able to output Dolby from TV to Soundbar (satellite TV) (Therefore, problem doesn't seem to be TV output)

Here is what does not work:
- I am unable to play DTS or Dolby audio (with passthrough setup)

Here is what has changed with the override:
- audio device properties does show DTS and Dolby as supported encoded formats (previously, none listed)
- Previously, when I played DTS or Dolby with my passthrough setup, XBMC would stutter and lag. Now, it plays the video just fine, but no audio seems to passthrough. My soundbar input reads as "No data". (whereas, when directly connected, it would read "DTS" or "Dolby" respectively, and with passthrough setup it does play LPCM and displays "LPCM"). I have tried different settings within XBMC to no avail.

As a note, I did reboot. And I am not sure if this is significant, but in the audio device properties, it says that the max number of channels is 2... I was expecting more?
Any help would be greatly appreciated! Please let me know if you need more info...


Edited to add that Dolby output works from TV to soundbar

For DD or DTS passthrough to work the application (XBMC) must send a non-decoded, DD or DTS audio stream (the latter should be accepted by the TV from what you say). That's all there is. Check that XBMC audio is accordingly set up.

"2 channels" is OK per SPDIF max bandwidth for uncompressed audio.
post #3776 of 3908
Thanks for your thoughts.
As per your suggestion in the OP, I tried using MPC-HC instead of XBMC (for a video file with DTS audio), and it appears to be outputting the audio as LPCM...
I have played the same file in XBMC with audio output directly through optical from HTPC to soundbar, and it outputs properly as DTS. Interestingly, if I do the same with MPC-HC, it still only outputs as LPCM...

Right-click on MPC-HC window during playback and select "filters". See that the audio filter being engaged is not decoding the audio stream. LPCM output means that the original DTS audio is in fact being decoded. Again check for a proper audio setup.
post #3778 of 3908
Thanks for the suggestion. Unfortunately, it actually replicates the same problem as when I use XBMC (outputs "No Data" to soundbar)

Here's what I just tried:
(with the following setup: HTPC -> HDMI -> TV -> optical -> soundbar)

1) loaded video file with DTS in MPC-HC
2) played with default settings -> outputs audio as LPCM
3) right-click -> filters -> LV Audio Decoder (internal) -> enabled/clicked AC3 and DTS -> stops audio playback (outputs as "No Data")

Any further thoughts would be greatly appreciated... This is truly frustrating frown.gif

Use LAV filters as preferred in MPC-HC and set LAV audio decoder to passthrough mode (by ticking all formats). It should definitely work, unless your TV won't passthrough DTS (only DD), in which case you might get no sound. If this is the case there's no choice of course but a TOSLINK/coaxial connection for audio.

Actually, if his TV can't handle DTS, he can use AC3Filter instead of LAV, since AC3Filter has an option to encode an AC3 stream via SPDIF:



In other words, AC3Filter can encode any stream into an AC3 and output via SPDIF.

You can read and experiment more here: AC3Filter
