Would I need to add this to the 1st or 2nd block ?

I tried changing values from the 1st block into a custom res like 1922x1078 to see if it would show up but it didnt show up.

Using regedit you can actually find the 2 EDID override flags and the data from the modified EDID is actually in there.

Is the checksum of the EDID blocks important ? How can you calculate it, anyone know ?

If I check Preferences for drivers there's no drivers loaded or they aren't needed.

I could only see my ATI Radeon 4870 drivers in DirectX test tool or in System32.

I have connected Analog monitor through DVI adapter and Sony Bravia through DVI dongle HDMI cable.Can't connect to Yamaha RX-V1800 receiver at all.
I'm using WinXP Pro SP3.So how do I change EDID.ini file if there isn't any ??
Why three monitors ??

The workourd in this thread only works in Vista, Sorry.

Should work in either, but I admit I am not certain whether ATI and/or Nvidia look for custom timings in block 1 or block 2 or both.

Checksum might indeed be your problem. Not positive, but I am pretty sure adding all the hex digits in each block must equal 00 (or more accurately end in 00). If you compute the difference between the old DTD you had and the new one you added, you should be able to just add that value to the checksum byte at the end of the block.

A great thread, thanks for all the info

I had my setup working by using the original EDID file and switching the receiver code to my amp Yamaha DSP-AX763 (EDID info as posted in another post), and keeping the Smasung monitor info and all was working, except that my monitor was recognised as a Sumsung when it is actually a 1080P Toshiba. (ATi card is a 4850)

So, today I thought I'd update my EDID file with my Toshiba info - it worked and my monitor is now recognised. However, now I only get Stereo sound in the audio configuration screen

I tried uninstalling the monitor in Device Manager and reinstalling the EDID with the Samsung monitor; but it still comes up as a Toshiba in the Device Manager - and I still only get Stereo

I wish ATi would just sort their driver pack out so we wouldn't need to mess about with all of this.

If anyone knows how I might be able to get my surround back I'd appreciate it?

Did you (re)install the Realtek ATI audio drivers, sounds like your using the Microsoft default driver.

Sure did. It displays in Control Panel > Sound: Realtek HDMI Output, ATI HDMI Audio, Working. No other sound devices visible (as before). However, one difference is that the icon shows a flat panel TV, with the green 'Default' tick.

I think it has something to do with the TV only having two speakers and it's getting all confused...

First time with PowerDVD 7.3 and WinXP it was possible to inject AC3 and DTS into HDMI by setting ATI HDMI Card as default in Sound Control Panel and selecting SP/DIF in PowerDVD it did the job. Driver was from ATI version 8.11.

Now things have changed and DTS and AC3 passtrough does not work anymore.

So I have taken the EDID data from the HDTV Set and edited the CEA-861 EDID bytes to incorporate some features that my receiver can decode as DTS and AC3 and the 5.1 speaker definitions. All other settings reffering TV configuration are kept.

So the edited EDID data looks like this:

Checksum is OK.

HowTo make CheckSum
Sum all values from block (result is in hex)
result is bigger than 2 digits
keep only 2 digits from right
sum + checksum = 0 (or 100 as hex)
this is the checksum
tested with first 128 bits and worked


I have made the *.INF file associated to those settings and I have installed this but nothing new happend.

I need a little different setup than most of you, but suffer from the same problem:

What I try to do is Video & 5.1ch -> HDMI -> TV -> dig. coax-out -> Audio-Decoder. This worked fine until I bought new hardware that takes care of EDID. So the TV actually CAN passthrough 5.1ch Audio. Currently, I can only select Stereo.

As you can see, the TV does not advertise 5.1ch capability to the PC (which is true, since the TV only has stereo builtin) but I dont care because I just want to passthrough so I get in-sync audio from whatever I input to the TV.

My Decoder box can decode 5.1 AC3 and DTS as well as Stereo (Dolby Pro-Logic II upmix).

Is that possible to realize? What do I have to change?

Hi,

thx for this interesting thread.

Does anyone know, if there's a solution for XP available somewhere?

ATI-Support just gives me hints that do not help :-(

Thx, Martin

VPN-User,even though the pc reads stereo it will still pass spdif or the hdmi out and you can pas it on from your tv to your receiver or what ever you use to decode.I use to have a Ati HD2400xt video card that was hooked up with dvi to hdmi adapter that came with the card.I ran hdmi to LG 47' HDTV and a rca digital out of the back of the TV to a Onkyo HT-R530 AV receiver.I used Power Dvd 8 Ultra with hdmi sound set to ac3 pass through.My dvd's would be in DD 5.1 or DD-EX and some Blu-Ray titles (DTS-HD) would read DTS+Neo6 in the Onkyo.It will pass through even though it reads as stereo.

stinman, thats how it worked with my previous onboard ATI X1250. I was able to play everything through HDMI and grabbing digital audio out on TV just by activating spdif on the PC. Seems this only works fine using older hardware.

No more with my new Intel MoBo DG54FC (Also previously tried ATI HD3200 onboard and nVidia 9200 onboard - didnt work either). Only Stereo is shown as available in Vista and only this can be played. If I play some AC3 files, I only get very loud noise or no sound at all.

Two questions:

1. Is there any potential risk involved just trying the ini file randomfoe posted in start of the thread? I mean, could this destroy my reciever or brand new KURO television? Somehow corrupt the original EDID data stored in eprom?

2. When llooking in my device manager when everything is connceted (AVR and TV) I have two "generic PnP monitors". Which one do exchange for the custom ini?

Just wondered if anyone had the same problem as me in relation to EDID provided by the display and connected non alterable components(e.g a receiver) instead of a HTPC to obtain certain resolutions/refresh rates. You may want to take a look at my post here:

Hi All

Starting to go a bit mental here, this looked like a good place to post to see if someone can help me out

I have a Asus board (P5E-VM HDMI) with the G35 Chipset, using HDMI to a Yamaha AX763 and then HDMI to a 32" LG LCD (32LB75)

The Intel TV Wizard sets me at 1280*720

My LG's native res is 1360*768

I can force this in using DTD Calculator and it looks great, but I loose HDMI audio.

I want to keep the audio over HDMI

I have a feeling that I need to override my EDID from the Yamaha to keep HDMI audio functioning? I see someone has posted the EDID for my AVR here but turning the raw data from my LG into the EDID is pickling my brain

Am I on the right track?!

I've attached my MonInfo results, any help or guidence would be greatly appreciated

Good news. I have been using an edited EDID monitor file for the last few weeks to get my Sony 4400ES and SXRD TV to function with sound. I had the problem with only getting 2 speakers in the configuration (no 5.1 or 7.1) and system bomb when i tried to test Dolby or DTS from there. Also, WMC wouldn't play sound and would crash when I tried to configure sound.

Well i just downloaded the new Realtek drivers version 2.13, both ATi version and Vista version as I have built on sound also from them.

All my problems went away and it is functioning perfectly.

I have a few unusual issues which I hope someone can help me with.

System:
Dell 8400
SoundMAX AC97 onboard audio
Sapphire Radeon HD4670
Catalyst 8.12 drivers
Sapphire Theatrix 550
Dvico Fusion HDTV 5 USB
Onkyo TX SR806
Vizio P50 HDM

Problems:

1 - First problem I worked around using the command line install of CCC. I kept getting "Catalyst Install Manager stopped working", so it wouldn't install. Maybe some one knows how to solve this also...

2 - I've tried the solution posted here and only get stereo. In Windows Sound configuration it shows HDMI LR Stereo as the only option - no 5.1 though in the features supported tab it shows Dolby Digital 5.1. When testing dolby digital it says "unsupported format" or something like that. This fix DID cause CCC to go from DVI to HDMI for the DTV tree element. I get NO windows sounds but Windows Media Player will output stereo music and play DVD's in stereo (PCM stereo only).

Do I need to install the ATI HDMI Realtek drivers even though I don't have Realtek audio HW but SoundMAX AC97 HW on board? By the way, I saw some new drivers with a 12/31/2008 date so I downloaded those but haven't tried them.

3 - An HDMI port went out on my Vizio P50 HDM TV and when they replaced it, I think they didn't reflash the EDID info since it shows a 32" size display and probably LCD vs. Plasma. I suspect the timings are all hosed and not right for my TV which could be causing all kinds of HDMI problems with my Onkyo 806 connected to it.

MonInfo as currently read from a 50" Vizio P50 HDM - clearly WRONG.

So how can I get the EDID information updated to the correct timing for this TV? I have searched a little on the web but didn't find the timing information and I'm not sure how I'd update it anyway. Use PowerStrip? I guess I can try to get Vizio to update it as a long slow solution. I know the panels native resolution is 1366x768 and it probably prefers 720p but don't know for sure. The current EDID shows a very low bandwidth 80MHz which i doubt is right.


Thanks to anyone who can help with one or more of these issues...
kemac's Avatar kemac 02:31 PM 01-01-2009
Yes, you need to install the realtek "ATI" audio driver in order to take advantage of the audio controller in your 4670, the default Microsoft controller will not allow you to configure more than two channel. This has nothing to do with your onboard audio since your using the 4670 for audio. So go ahead and install the drivers you downloaded assuming they are the "ATI" realtek driver that you downloaded.
Don Maurer's Avatar Don Maurer 04:50 PM 01-01-2009
Yes, the Realtek hd audio drivers made the sound go to 5.1. Thanks!

The ATI support guy (level 2) said I didn't need them since I had a SoundMAX onboard HW. I'm shocked they are so bad.

Now to get the installer to work and my EDID updated on my Vizio. Anyone have a Vizio P50 HDM who can run MonInfo for me?? At least I'd know what it SHOULD be.

Thanks

Hi guys, after reading all your posts and trying different possibilities, my sound output through my AV receiver still does not work.

I have ran moninfo to get the raw data for my Panasonic TH-50PZ80U and did the same connecting only the Yamaha RX-V863 and hitting the F5 key to get the info.

In the device manager I see the MS EDID Override inside the Monitors section, but still not getting any sound.

When checking in Playback devices it says ATI HDMI Sound not plugged in ?!

I'm running Vista X64 with the Palit Radeon HD 3870...

Can anybody help me ?

Thanks,

Hi There,

I also am struggling with no Audio over HDMI issue for about a year now.....my setup is as follows,

TV - LG 37" LB1R
AV - Onkyo TX - SR605 attached to 5.1 KEF 2005.2 .....the Eggs as they are called..

and HTPC

MB - Gigabyte P35C-DS3R
GPU - HIS RADEON HD2600XT DDR4 with ATI DVI-HMI Dongle.

OS VISTA Ultimate 32bit

with my initial efforts of trying to get audio over HDMI working.....i've just given up and have been using audio over SPDIF optical to the receiver since which works perfectly ...but from time to time i try and install that new Realtek HDMI driver release just to see if it works.....with ..as most of us can testify ....NO RESULT...

I also bougth another card recently for my other pc, a ASUS EAH 4670 with native HDMI......tried and achived same result....no Audio over HDMI.....
new 2.13 realtek driver, new catalyst drivers, etc, etc....

I've come up with this EDID post and thougth of giving it a try, i've build the .inf file correctly with just one line etc etc the 1st block for TV, the second block for receiver Extend Info, etc....but although the CCC now correctly displayed the TV Information as LG 37LB1R and not TX-SR605....one thing was not working ......AUDIO.(no Stereo, no 5.1, nothing)...as usual...

Then at 3h30 AM in the morning completely tired, in a desperate attempt i've tryed the solution that someone here also had sugested of just using the .inf file AS IS, that is on the beginning of the post..

And thats what i did.....i've rebooted the pc and , what the hell, I HAD AUDIO, ...didn't try 5.1 but stereo was working...and i had one particular problem with the display.....screen was split in half....image on top and bottom...i guess this should have something to do with the embedded data from the samsung that is 46 " being my LG just 37"....

today ill try to overwrite the Samsung data with my LG data and keep the second part of the Yamaha receiver....to see if it works...with no display issues...

Now question is ......Why the hell does it work with edid Data from a samsung monitor and a yamaha receiver, and doesn't work with my EDID's....?????

Two possibilities:

(1) your INF file was badly constructed
After installing an INF and rebooting, you should run MonInfo again, select the EDID from the list of Display IDs that is postmarked [Registry*] and make sure its the one your intended in your INF. If it isn't, check your INF again.

(2) your Onkyo EDID extension bloc is inadequate
If the INF is not the problem, compare the actual data fields for the Yamaha extension bloc with the Onkyo extension bloc.

Try the inf file in the first post, if it works you know you have an issue with your custom inf, otherwise its something else.

Hello.. And thanks to RandomFoe and a bunch others

Im trying to get 5.1 sound through my Sony laptop (Ati 3470) to my 663 AVR, but with the INF installed i can only get L/R channel PCM to lit up on the 663 when playing AC-3 coded media. Maybe not so surprising because i can´t choose anything besides "Stereo" for the HDMI device, even with Realtek´s HDMI drivers installed.

But if i press the test buttons for DD/DTS sound in the properties for Ati HDMI Audio the AVR senses the signal and switch on all the channels.

Any suggestions?

Regards.
kemac's Avatar kemac 10:59 AM 01-02-2009
What are you using to play AC-3 media? Have you checked your player settings to make sure its sending AC3 as bitstream?
Deputy_1's Avatar Deputy_1 11:27 AM 01-02-2009
I use "Media Player Classic home cinema" & "Zoom Player" and a AC-3 filter from ac3filter.net/

AC-3 Filter is telling me this when im playing a MKV

Input format: DTS - 48000
User format: PCM16 - 0
Output format: PCM16 3/2.1 (5.1) 48000

That would explain it, thanks! your player(s) are generating 5 channel PCM when the 3XXX cards only support 2 channel PCM.

Off topic for this thread but you need to figure out how to just send the raw AC3 and skip the conversion to PCM via MPC or ZP. Good Luck!
Deputy_1's Avatar Deputy_1 11:46 AM 01-02-2009
Seems i have to learn some new things then

Thanks kemac, i appreciate you taking the time.
kemac's Avatar kemac 11:59 AM 01-02-2009
Their should be a way to just passthough the AC3, might just be a setting in AC3 filter or in MPC/ZP or both. If I come accross anything that might be of help I will send you a PM.
pimpinonline's Avatar pimpinonline 12:52 PM 01-02-2009
This worked like a champ for me. I just used the original .inf file attached to this thread, worked without issue.

Also, one thing I would like to note. This didn't work for me until I disabled my onboard audio in the BIOS. If you are having troubles, you might want to start there.

I have a Samsung A650 50" Plasma and a Sony STR-DG920 AVR hooked up to my Dell XPS 420 ( aftermarket ATI HD4850 video card ) with dual cable tuners. I have full Dolby Digital DTS 5.1 sound ( 7.1 would probably work if I had a Blu-Ray player ). The only thing I haven't gotten working is the Divx movies I have on my machine. Digital cable works fine with full 5.1 sound, but my movies ( AC3 encoded ) don't work, they just play in stereo. I assume this has something to do with my AC3Filter configuration. Before this solution, I was using SPDIF out, and had AC3Filter configured for that, so I am thinking I might just need to adjust some settings. If anyone has any suggestions to get my AC3 audio working for my Divx files, feel free to shoot me a line.

I also noticed that when I tried to set my sound card configuration to 5.1 within the Windows Control Panel, it freaked out, playing a hoffific screaching sound. I am also trying to figure out why that is.
