You have to do each separately and then take the correct half of each and merge the results to create a custom EDID. Just follow the directions posted earlier in the thread.

Does anyone know the EDID codes for a Denon 3808? I've been driving myself nuts trying to figure out why hdmi audio isn't working from my HD 4670, I think this is the answer.
post #303 of 3078
Got it working with poneer 5090h, harman kardon 255 and asus 4350 after reading through the instructions carefully. Lot of misstakes done during the process. Would be great for newcommers if someone could make a graphical illustration of what needs to be done in monoinfo and notepad. Exactly what goes where...


Before I made the custome inf I used the one supplied by randomfoe. No problem, didnt seem to hurt my hardware. However, the tv looked kind of blurry in 1080p@24/23. To my surprise the 255 worked flawlessy in terms of sound. This kind of make sense as the yamaha amp is probably very close in terms of hdmi specs to my harman kardon.

Consequently, if you can not get it to work using youre own reciever parameters a quick fix might be just substituting the first line in randomfoes INF(the one for TV) and then keeping the rest....

I have an HK354 and I cannot get EDID info from it. Could you post the EDID lines you used for the audio portion, or maybe your whole .inf file if that is simpler? From an EDID point of view I think the 255 and 354 should be the same. Even if the are not, its better than what I have now, which is nothing :-)

Here you go, the edid values for harman kardon 255:

In the EDIDoverride file (second line) it starts with "HKR,EDID_OVERRIDE,"1",0x01,"

then this follows:

post #308 of 3078
Just curious. Has anyone got this to work with an NVIDIA card?

I don't need it ATM but thought I'd have a play just in case (I'm sad like that ) but no luck.

What I did as a test was take the EDID from my Tosh TV, edit the SVD section in the extension block by replacing the value for 720x480i with the value for 1920x1080p@ 23.97/24Hz, recalculated the checksum and then added the blocks to the INF file (one I created with some non-essential data removed and the one kindly posted by Randomfoe in the first post just in case) and tried both.

The driver installs fine (display now listed as MS EDID Override in Device Manager) and I can see that the EDID override entries have been added to the registry however, 1080p24 still isn't listed as an available resolution in the NVIDIA control panel which suggests the override values have been ignored.

Hence the question.

I should point out that I didn't expect the new 1080p24 resolution to work (my TV doesn't support it) but if the override was working I would have thought it would be selectable (and probably result in a black screen).

Below are the original and modified EDID extension blocks

I've also attached my modified INF and the modified INF based on RandomFoe's sample (saved as .txt for the purposes of posting only).

If anyone spots a mistake in either my EDID calculations or the INF(s) please let me know. If not I have to assume this is "no go" for NVIDIA (which I must admit would seem odd).

TIA.

Wo0zy,

Perhaps adding 24p to the DTDs in addition to (or instead of) the SVDs would work?

Aye. Thanks mate. Somehow I thought you'd answer the call

Was just hoping someone could confirm NVIDIA success before doing the sums. If not I'll give it a go next weekend and report back (may help me or someone else in the future).

Happy New Year my friend. Hope it's a good one for you!

Did santa bring you your new components?

All the best.

post #311 of 3078
And to you.

Alas, I was not granted my Christmas wish of new components, and some other budgetary issues make it clear that when I fried my mobo in December I may have fried my HTPC plans for the first half of this year. Had some gift certificates from Amazon which got me partway there (replacement hard drive), but I'm still in need of an IGP motherboard and quiet power supply.

I'm still holding out hope my own personal Finance Minister will approve an addendum to the budget, but for now I'm just watching the vendors for a ridiculous discount.

post #313 of 3078
OK, I just found this thread and attempted to do as the first post suggest. I'm using a Samsung LN40A750 and a Yamaha RX-V663. I originally used my own gathered EDID data from hooking the TV directly to the HTPC (used this as the TV's EDID) and then I hooked the HTPC to the V663 (used this as the AVR's EDID). When I loaded this INF, nothing changed... CCC still detected display as DVI. Then what I did was use an INF that contained my gathered TV EDID (connected directly) and put that as "0" and then I used the already supplied "1" data that was in the INF in the first post... which is supposedly for a V663. Loading this INF CCC sees the display as HDMI. HOWEVER..... Now I get no sound what-so-ever. I'm trying to pass the audio off my motherboard via Digital Optical rather than through HDMI, because thats the only way to get 8 channels as the onboard HDMI only does LPCM 2.1. But at the same time I want CCC to see my display as HDMI so I can set Pixel Format (which isn't available under DVI). So the questions are.... what the heck am I doing wrong? Is it possible to get CCC to see my display as HDMI (when connected as: HTPC -> V663 -> TV) and at the same time pass audio from the motherboard to the V663 via Digital Optical? I think the receiver is only allowing for audio to go over the HDMI cable and not allowing me to do VIDEO over HDMI and AUDIO over Optical. Is this the problem? Anyone know if I can do this on a V663? If not, anyone know a receiver that can do this?

Thanks for your help.

SPDIF (which is what your "digital optical" is) can only pass 2-channel LPCM and compressed formats such as DD and DTS. HDMI is the only way to get 8-channel LPCM so if your graphics card/IGP doesn't support this then sadly you're out of luck on that front. What chipset are you using?

Forgetting that for a moment, you should still be able to send audio via SPDIF even if the HDMI connection advertises audio support. I assume you have tried changing vista's default audio device? It sounds like it probably changed to the HDMI device once the EDID override was applied. Try changing it back.

Wo0zy,

Yes I it is set to use Digital Optical as default, it never changed. All the changed is it now shows REALTEK HDMI Audio as connected. If I play sound on the system the little green bars on the right of the devices moves next to Digital Optical.... just no sound comes out.

The chipset is 780G. The actual motherboard is gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ClassValue=Motherboard&ProductID=2758&ProductName=GA-MA78GM-S2H (rev 1.0)

Back when my display was being detected as DVI (and obviously the V663 wasn't getting audio via HDMI) it was getting audio over Digital Optical and all five channels lit up on the receiver. Now that it's just HDMI audio only two channels (LF, RF) are lighting up on the receiver. Also, in the motherboard's manual it says the only way to get multiple channel sound out of the motherboard is via Digital Optical or regular Analog 7.1. Why do you say that Digital Optical output can only pass 2-channel LPCM? If both HDMI and Digital Optical both did the same thing, what would the point be?

Thanks for your help, just trying to make sense of all this.

Maybe you can remap the audio input associated with the HDMI port on the AVR? You can do that with Onkyo so guess you can with the Yammy. Don't know.

Anyhow, SPDIF can only handle 2-channel LPCM or compressed multi-channel formats (DD or DTS). It doesn't, and will never (AFAIK) have the protocol support to do anything else.

What this means to you is that you can achieve exactly the same via the HDMI output from your board if it's configured correctly and all the correct drivers are installed so I'd focus on getting this working and save yourself hooking up the extra cable.

The supported format limitation via your HDMI output isn't an HDMI spec limitation but a chipset issue. HDMI CAN do much more however, the best that can be achieved from a Any PC ATM (excluding what can be done with the Asus Xonar (in theory)) is multi-channel LPCM and AC3/ DTS. NVIDIA's 8200/8300 and 9300/9400 chips can do this as can Intel's G3x/4x chipsets and ATi's discrete 4xxx series cards.

The MoBo manual is correct but by multi-channel it means compressed formats (DD and DTS) via SPDIF or decoded discrete channels via analog.

Does that make sense? Not sure I've explained it clearly as I'm short on time.

One last thing, in order to get your HDMI output to support DD and DTS you'll need to ensure that you've installed the ATI HDMI audio driver as well as the graphics driver. You can get it from the Realtek website. If you've already done this make sure DD and DTS are selected under "Supported Formats" in the HDMI playback device properties.

Hope this helps.

Wo0zy

Edit: Should also add that this assumes your EDID extension block correctly advertises support for all the formats you need via its SADs (Short Audio Descriptors)

Didn't read your last post, just posting an update real quick. I did some reading in the manual today and I was able to set the audio input to OPT/COX rather than HDMI for the input I'm on... so I'm now once again getting audio over Digital Optical, so got that sorted. Reading your post now...

post #319 of 3078
Wo0zy,

OK. I understand what you're saying about the AMD/ATI/HDMI limitations and then lack thereof. Let me just say, that right now I'm only using the onboard audio and video.. I don't currently have a discrete ATI card. I was considering purchasing a ATI 4550 to be able to get 8 channel LPCM over HDMI. I just wanted to make sure that this Yamaha receiver allowed me to select audio on different inputs and didn't just force me into audio over HDMI if it was being supplied there (like the crappy Samsung HTIB was doing).

Also, I went ahead and enable DTS/Dolby on the Realtek HDMI Audio and the receiver still only shows output to two speakers over HDMI (only RF, LF light up) whereas when I choose the Optical input all 5.1 channels light up (this one is setup with Neo:6 in Vista ). Another thing.. on the Realtek HD Audio Manager panel for HDMI output I'm unable to set the speaker configuration to anything more than Stereo and there is no tab for DTS connect. Is this a limitation of the onboard audio over HDMI? If I were to get a 4550 would this tab subsequently contain a DTS Connect tab and allow me to choose other speaker configurations?

Thank you.

DTS Connect only works with the main onboard audio codec. It isn't available via the HDMI audio device.

However, this doesn't really matter unless you're into gaming Basically DTS Connect encodes audio into a compressed DTS format "on the fly" and "bitstreams it out of the SPDIF port. This isn't the same a multi-channel LPCM as you're no doubt aware. If the source is two channel only there may be some other DTS technology built in to the audio codec (Neo:6?) which creates the extra channels via matrixing before encoding to DTS and passing the results as bitstream to the AVR. Any source already encoded as DD or DTS bypasses the process (or should) and is bitstreamed as is. So, unless you have sources that start as discrete multi-channel (such as games) the results of this process will be no different to passing the 2-channels as LPCM and letting the AVR matrix to multi-channel.

Did you do the DD and DTS "test" when you enabled support? If so did the DD and DTS indicators light up on the AVR? If they did you're good to go. Try playing a DVD movie with a DD soundtrack and see if you can hear all channels. If the DD indicator comes on there's no reason why you shouldn't.

You can't config more than 2 speakers on your HDMI device because that's all it supports (2-channel LPCM). This has nothing to do with whether or not you can bitstream compressed multi-channel formats combine this information with what I've said above and you should be getting the picture.

......Or you could just leave things as they are now. It really doesn't matter other than the extra cable. It will do if you get your 4550 though

post #321 of 3078
wo0zy...

I'm typing on an iPhone so bare with me. So let me ask a few more questions...

Would there be any advantage to getting a 4550?
With what I have right now (and considering what's on the market) I can't bitstream TrueHD or DTS-MA right? If not the best I can do (if using HDMI and TotalMedia) is decode it in software and pass it out as 2 channel PCM right? If I use Optical and the software can decode it to 5.1 I'd gain a few channels right?
If I get 4550 I'd still need the software to decode and then i'd get 8 channels over HDMI right? So in essence I'd just gain the advantage of using one less cable right? Or would I also gain unmolested audio.... Meaning no DTS connect (matrixing)?

What would the best possible HTPC setup well using my current AMD motherboard plus any additional cards I may need to get true 5.1 or better sent to the receiver from Blu-ray discs that have DTS-MA and TrueHD audio tracks?

Thanks!
post #322 of 3078
I need help with an issue which is probably EDID related, but I don't know for sure. The issue I have has to do with switching inputs on my TV while the HTPC is on. Often times, when I switch the input back to the HTPC, I see a window which is 800x600. When this happens, I do not get the option of changing the resolution back to 1920x1080 in the Graphic Properties dialog. There are some hacks to get this option show up again, but I would like something which is automatic.

I just want 1080p output at all times. I created a custom inf file using PowerStrip, but I get the same problem. Any suggestions on what I can try? I am using an ASUS P5E-VM motherboard.

Thanks,
Sumit.

If I get 4550 I'd still need the software to decode and then i'd get 8 channels over HDMI right? So in essence I'd just gain the advantage of using one less cable right? Or would I also gain unmolested audio.... Meaning no DTS connect (matrixing)?

5.1 LPCM over HDMI is capable of higher bitrates than 5.1 over an optical or coaxial digital connection, so in addition to being able to do 7.1 LPCM, you'd also potentially have better audio quality too. Converting TrueHD or DTS-MA to LPCM is essentially the same as using WinZip to unzip a file, so you aren't losing any sound quality by having it done in your PC instead of in your surround sound processor. The digital to analog conversion will still happen in your surround sound processor. Whether you'll be able to appreciate the improved quality you get with LPCM is another matter and will depend on your equipment (speakers, amplification, surround sound processor, your ears, etc.).

When this happens, I do not get the option of changing the resolution back to 1920x1080 in the Graphic Properties dialog. There are some hacks to get this option show up again, but I would like something which is automatic.

I just want 1080p output at all times. I created a custom inf file using PowerStrip, but I get the same problem. Any suggestions on what I can try? I am using an ASUS P5E-VM motherboard.

Not sure if you're using an ATI video card (or chipset integrated on your motherboard), but if you are, try disabling the ATI External Event Utility service on your system in addition to using the override trick discussed in this thread. Doing so may improve your situation. In my case, it did improve the situation, but has not completely fixed it like I initially thought. My HTPC still loses the EDID info at times when I switch inputs on my surround sound processor or turn it off. I've ordered an HDMI Detective Plus which I hope will solve the matter for good.

Would there be any advantage to getting a 4550?
With what I have right now (and considering what's on the market) I can't bitstream TrueHD or DTS-MA right? If not the best I can do (if using HDMI and TotalMedia) is decode it in software and pass it out as 2 channel PCM right? If I use Optical and the software can decode it to 5.1 I'd gain a few channels right?

What would the best possible HTPC setup well using my current AMD motherboard plus any additional cards I may need to get true 5.1 or better sent to the receiver from Blu-ray discs that have DTS-MA and TrueHD audio tracks?

Thanks!

Sorry mate. This is getting a bit OT for this thread so I'll keep this short.

Best results for BD playback from an HTPC will be achieved by passing multi-channel LPCM to your AVR. This is true regardless of whether the original disc has True HD , DTS-MA or MLPCM soundtracks. This is the advantage a 4xxx will give you over what you've currently got (if you plan on keeping the rest of your setup intact).

Whatever you do with your current config will involve additional decoding and/ or re-encoding steps to achieve a lesser result. Whether you can hear the difference will depend on a number of factors

Alright Wo0zy. Thanks for all the help.

I'll probably end up getting a 4550 so I can do 8 channel LPCM and hopefully I don't need to come back to this thread in order to get that working (a la EDID override).

Now the other thing to consider is if I should keep my new Yamaha RX-V663 since it clips BTB and WTW. I'll go beat that horse elsewhere...... :P

Thanks again for helping me to understand the basics.

Not sure why I bothered to answer your question... are you only accepting replies from Wo0zy?

Actually, you don't in all cases. The combined EDID you can get from Moninfo (providing it can do a real time DDC call) produces a perfecly servicable EDID. You just need to ensure you split the primary and extension block in the INF correctly.

I've done this a few times now and it works fine.

If you find that Moninfo is only reporting "Registry Stored" data (which doesn't seem to happen with the latest version and if it does uninstalling then reinstalling may fix it) then you may find that the extension block is a repeat of the primary block (which is what happens in situations where problems occur and is the fault of the ATI drivers EDID detection method) THEN you may have to resort to this tactic.

In short, overcoming the "detected as DVI and therefore no HDMI audio" problem doesn't involve "fixing" broken EDIDs (in most but not all cases). It does however require ATI's EDID detection process to be bypassed.

I'm sorry gsr, I as reading through an iphone and was just scrolling to wo0zy's posts at the time. Thanks for your reply as well. I've worked out most of my EDID issues so far. Still don't know why the EDID information I obtained from my V663 doesn't seem to work in the same fashion that the OP's does. Wish I could explain that.. but as long as it works I suppose.
