3d vision with home theater setup, too many headaches
I just bought an nvidia 3d vision kit. I'm extremely, extremely disappointed to find out how much of a pain it is to get 3d vision working with my system...
I'm using an optoma HD66 (updated firmware which works with 3d vision)
My receiver is an Onkyo tx-nr708, Hdmi 1.4a and 120hz capable
My laptop has a gt460m
I'm sure you've all seen the problem by now, when I try to use the setup wizard it sees the receiver and not the projector. When I use an acer edid override it sends 3d but won't output sound through hdmi.
I've attempted grazz's edid override which enables both, but I couldn't get past the wizard no matter how many times I tried it (maybe bc nvidia's drivers are much newer than when that solution was posted...)
At this point, I don't know what to do. I'm considering getting a Gefen HDMI detective to relay my projector's edid to the laptop, but if I did this wouldn't it stop outputting sound through HDMI just like with the acer edid override?

Yeah. I basically gave up in the end.
I have a hdmi switch box to allow me to connect directly up to the projector and I use spdif audio straight from the motherboard.
I really hate the hoops that we have to jump through to get this stuff to work.
Thank you for the response...although at the same time I sort of died a little inside and gave up hope. My laptop doesn't have any audio output except headphones or hdmi...so my workaround options are limited unless I build an HTPC.
Did you happen to try using the gefen, by any chance? I'm probably going to try installing some older nvidia drivers, doing some additional diagnosis to make sure the base EDID I'm working with is actually good (from the optoma)...once I'm not so annoyed by it already :-x

I wonder what the underlying problem is, I had no problem with HDMI audio with 3DTV Play
with my VG278H and Samsung HTiB 5550 when I tried some time ago.
Although I am stuck using two separate cables using 3D Vision as you can't combine HDMI audio and
dual link DVI. There are definitely laptop soundcard upgrades that offer other outputs.

Thanks to everybody using my assembler it warms my heart.
To have a critical piece of code that everyone can enjoy!
What more can you ask for?
The only soundcards I can think of that would offer other ouputs (I'm assuming they exist, at least, never had to purchase one myself so I never looked into it) would be a usb soundcard. I could run dual outputs that way most likely, worst case scenario
The problem with my receiver is the computer sees it as a receiver, and nvidia won't enable 3d because it doesn't see the 3d ready projector on the other end. This would be solved if nvidia simply allowed me to enable 3d vision for the onkyo.
From what I've seen, almost everyone using one hdmi through a receiver (to a projector at least) had this problem. Some had success modifying the drivers for their projector, and then installing those drivers over the receiver's, but that was some time ago and I don't know if it's my particular setup hindering me or my driver version (so I'm about to downgrade to the last known working driver config for this setup)
EDIT: I'm sick of wasting hours on this, I'm angry with nvidia, this is silly...I'm just going to try to sell my basically new 3d vision kit and go the easy route. Get a 3d-xl box for my projector, set it up after the receiver, and use my ps3 for 3d. If somebody decides to buy my kit in the next few days

From your first post it sounded like you never had it working. So which driver would you downgrade to?
If you did have it working you could obviously stay with that driver and avoid problems.
I'm suprised that Nvidia would break anything connected normally.
Any EDID override solution could obviously break with driver version.
I don't know which point in the chain is broken as my computer obviously sees the
display endpoint so it's clearly not hidden behind my reciever.
I'm obviously not running 120hz over HDMI so I can't say much about the 3D Vision situation.
In most of the EDID, the audio information is carried in the extension block.
The EDID override you used more than likely did not contain the extension block, almost every EDID I see posted around are missing it.
Even if you did use a Geffen capture device to get the EDID straight from your projector, you'd be limited to whatever audio data descriptors were present in the EDID. Say if the projector has only a single speaker, then the EDID may only have a descriptop for mono support.
One of the best things you could do, is merge the two EDIDs. There's a thread or two here in the forums about doing so. You'd use the video and display descriptors from your projector and the audio descriptors from the receiver. Although it's not as easy as it sounds, because most EDID programs will not let you capture the the extension block from the registry.You'll need spend time researching this, but it is very doable.
Here's a link to a thread that will shed some light on doing so, although it's not the same issue as yours.

yes, that's the modified "driver" file I tried doing. when using the EDID from the projector, I did in fact get 3d to work just fine...however with no audio. when I followed the steps to merge the two EDIDS, i couldn't get it to output 3d but audio worked fine. almost as if it didn't make a difference over using the receiver's standard edid. (i checked my steps repeatedly and tried the process probably a dozen times, did a lot of research on that part)
and that's the major thing i assumed and was wondering about the geffen, so thank you very much...you saved me from spending 85 dollars on an item that wouldn't really work.
i think my best solution (if using nvidia 3d vision) would be to build an htpc with an intel ivy bridge, use the hdmi from the motherboard to output sound to the receiver, and use a video card to output to the projector. i wanted to avoid spending all that money if possible, obviously.
@flugan, i never had it working properly, but i started out with the latest drivers available. i thought that possibly uninstalling the drivers, wiping all the information, and reinstalling to older drivers that the workaround was known to work with could help...but it's hit a point where i'm exhausted with playing around with it lol

Why use the Acer EDID? If it contains data descriptors for VGA or DVI, it will not send sound.
Have you used the HD66 with 3D Vision via HDMI? If so capture your EDID from it and ditch the Acer EDID.
There are seperate EDIDs for each input descibing the capabilities of each.
VGA EDID requests "Analog" video.
DVI EDID requests "Digital" video and no audio.
HDMI EDID requests "Digital" video and audio.
long story, but it started with my initial troubleshooting. first i ensured i had new/good and 1.4 hdmi cables. then i tried using the acer edid override because older optoma hd66 projectors had fault firmware and were not nvidia 3d vision compatible.
with firmware updates, they were.
in the end, i did pull the edid from my projector (after ensuring 3d worked when connecting directly)
and i attempted merging both the edid of the acer (which i knew worked for video via receiver before without audio) with the receiver = no success, and attempted merging the edid of the optoma with the receiver = no success
i don't know all the ins and outs of edid, although i'm fairly certain i did everything properly, so it's possible i read a guide wrong.
from what i gather, the guides told me i basically had to modify the Overridden-edid_addreg,
they told me to take the HKR, EDID_OVEERIDE, "1" code, along with everything afterwards, from the optoma projector...and put it on the onkyo receiver's edid. i'm assuming this portion is for the video, leaving the edid_override "0" for sound.
then after adding, install it as a driver for the hdmi that the receiver's connected to.
just to ensure i did everything properly
edit/update: i did some looking around, found that the onkyo 608 is actually listed as nvidia 3d vision compatible...mine is an onkyo 708, same audio and video processors pretty much. if i could get an edid from a 608 and run that with my 708...theoretically the problem should be solved? as in, would the nvidia drivers recognize is at a 608 instead? (i'm at work right now so there's no way of testing until later)...i already compared my edid override with others' whose have worked and i did in fact edit the transfer block correctly
