Unlike various speculations, G45 seems to be launched on time if this article is true.

And an AnandTech editor Gary Key's comment:

Thanks for the news about the G45. For what I want, it is a pretty minor upgrade from the G35, so I am glad that I didn't wait six month.

It's also nice to hear that the next version of the Intel drivers will fix some of the HDMI bugs.

Thanks. I hope you can influence Intel to do something with this. I'm planning on using a HTPC for high-end audio purpose and from what I've read Vista is useless for that at the moment. But at the same time I really would like Blu-Ray to work.

An AMD motherboard could have been the answer, but it seems like the AMD processors produce too much heat for my HFX mini cabinet.
Why is the world so diffucult.

Is there a reason to wait for the G45?

An AMD motherboard is the answer! Acutually the heat output of an AMD system may be better than a G35 system. These photos are a GeForce 8200 mGPU motherboard system at CES 2008. The total system power consumption is less than 60W when playing back Blu-ray Disc contents.

E8400 @70% CPU usage: 23W
G35 + ICH9R: 32.3W (TDP)
Total: 55.3W

Athlon X2 BE-2400 @30%: 27.5W
GeForce 8200: 14.3W (TDP)
Total: 41.8W

Low power consumption of the Intel 45 nm processor is nullified by higher CPU usage and the 90/130 nm chipset. The price difference is also significant.

E8400: $183 (@1000 qty)
G35 mb: $135
Total: $318

BE-2400: $100
8200 mb: $80
Total: $180

Hi Gris, I have the same problem as you and everything I've found and tried so far has not worked except I did read in here somewhere of some people fixing this problem by doing a clean install of Vista(ie format hard drive then install Vista). I haven't found the time to try that yet, I'm kind of hoping the next intel drivers will fix the problem and/or Vista SP1.

Perhaps your TV or AVR is not supplying any audio EDID info, and that is why you are not seeing HDMI audio in the sound applet. This is just a guess. If you have any other output devices that accept an HDMI signal, it might be worth trying them.

My Denon 4306 is only reporting back that it is 2 channel. I posted my EDID information hoping someone could verify that it is "faulty". I hope there is a fix for this because I have gotten spoiled with the flexibility of HDMI.

Dave, thanks. I read some more of this thread again to get more info on EDID and back on p.6 and Archibaeil says "Go to the Intel Graphics Tray, click on the Information button, then click "Save to Disk." Open the resulting file (Diagnostic Report.txt, I think) and post the results here. That contains your EDID information-- the info your HDMI port has learned from your monitor and/or receiver."

Well, I don't seem to have An Intel Graphics Tray, or at least if I do, I can't find it. This is likely my problem. Where do you find the Intel Graphics Tray and if its not there, how/where do I get it? - Anyone?

Hi Darren, yeah this is so frustrating - I understand why people have already moved on\\back to other MB's. But the promise of this MB is so good I'm determined to stick with it and try to at least get some audio out of the Hdmi. I don't think a fresh Vista install is the answer in my case as it is already a fresh install to start with. I think its probably something to do with the missing Intel Graphics Tray & maybe other factors too. Note: Vista SP1 didn't help.

There is an option that allows you to hide the tray icon. However, you should also be able to get to the Intel graphics applet from the Control Panel. Also, you might see an option to open the Intel applet by right-clicking on the desktop, and it is probably in the Programs menu too.

If you can't find it anywhere, I might begin to suspect that the drivers have not been properly installed, which would also explain the missing HDMI audio applet.

Oh, that graphics tray, yeah, I have that one, (brain lapse) . Anyways, I looked at the EDID and my Hdmi tv shows up OK there (& the picture's fine) but I couldn't see any audio info. there (maybe Intel needs an Audio tray too).

To re-cap, the Hdmi audio driver (2035 & also tried 2034) is shown (in Device Manager) as functioning properly but I'm still not gettting audio of any type from the MB's Hdmi to my TV. What gives ??????
Btw, I have this same problem on both P5E-VM HDMI pc's I'm setting up now - one with Vista32 & one w/Vista64.

You might want to try posting your raw EDID data. Wo0zy and Archibael are the experts here when it comes to decoding EDID info.

From the "Custom Resolution Tool for Intel Graphics" thread:

One of the most accurate (for your particular monitor) would be by grabbing the EDID data from the Intel Graphics Tray Information button (choose "Save to File" and the raw EDID will pop up).

Dave, going on your first recommendation, I unhooked and dragged everything upstairs & plugged back into my new Toshiba lcd TV. Worked like a charm Don't know why it wouldn't work on my 1.5 year old LG TV (w/2 hdmi inputs, neither worked for this but work OK w/Hdmi DVD players) - could it be because of a different Hdmi spec? If so this may explain why a lot of people seem to be having similar problems - hope the new Intel Hdmi driver solves this compatibility problem (when is it due?).

I guess that is good news. At least your Asus boards are OK, and you are not doing anything wrong.

I appreciate that Intel is trying to follow the HDMI spec and make everything easy for us by configuring the video and audio based on EDID info, but the hardware and software are not ready.

With my media player software, whether it is PDVD, Showtime, or Windows Media Player, when I switch the HDMI signal, either at the Onkyo or using a Monoprice HDMI switch, the Intel drivers detect a change in EDID and the media player gives me an error message stating that there is a problem with the audio driver. Intel should give the user the option of ignoring EDID and allow the user to select the video and audio output parameters.

Regarding your specific question about HDMI versions, Intel HDMI audio works with my 2.5 year old HP MD5880n DLP (HDMI v1.1), and my six month old Onkyo 905 (HDMI v1.3a). The G35 itself has HDMI 1.2a. When connected to the HP, I can only select 2 channels 16/48. When connected to the Onkyo, I can select 8 channels at 24/192. I don't think the issue is the HDMI spec level, I think it is EDID info provided by your output device.

You might want to check the thread for your TV and/or AVR and see if there are any firmware updates that will fix the EDID info supplied by the device.

I find that surprising. My general impression is that the new Denon's have fewer bugs than the new Onkyo's, and I would have expected that Denon would have gotten the EDID info right. Also, Denon provides online firmware updates, so it should be easy for them to fix this problem.

Dave, yes it was great to finally hear sound from the Hdmi, thanks for your help on that! Follwowing is the faulty TV's EDID, (I left out the info. for the monitor which I also had connected via D-sub & just left the problematic Hdmi TV info.) I hope they can make something out of it. I monitor the thread for the TV (LG 42lc2d) and there's nothing about any new firmware there so I hope that's not the problem because this is the TV one of the HTPC's is for & it doesn't appear to have any f/w updates available.

Gris,

I have never done this before, but I will take a crack at it using the Wikipedia article. Hopefully someone will point out any errors I make.

The audio data is stored in the CEA EDID Version 3 Timing Extension block, so we do not care about the first eight lines of your raw EDID info.

The portion we care about is:

Quote:
02 03 15 f1 46 84 05 03 02 20 22 23 15 07 50 65
03 0c 00 20 00 8c 0a d0 8a 20 e0 2d 10 10 3e 96
00 c4 8e 21 00 00 18 8c 0a d0 8a 20 e0 2d 10 10
3e 96 00 13 8e 21 00 00 18 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 35

Bit 6 of byte 03 (the first red byte) confirms that your TV supports basic audio.

The group of red bytes (15 07 50) specify that your TV supports 6-channel AC-3 sound at 32, 44, and 48 kHz. That is the only audio Data Block Collection that I see. As far as I can tell, your TV's EDID does not specify any PCM modes.

In contrast, here is the same data from my TV:

Quote:
02 03 16 71 23 09 07 07 47 85 10 04 22 20 03 07
65 03 0C 00 10 00 02 3A 80 18 71 38 2D 40 58 2C
45 00 C4 8E 21 00 00 1E FA 1C 80 3E 73 38 2D 40
7E 2C 45 80 C4 8E 21 00 00 1E 8C 0A D0 8A 20 E0
2D 10 10 3E 96 00 C4 8E 21 00 00 18 8C 0A A0 14
51 F0 16 00 26 7C 43 00 C4 8E 21 00 00 98 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2D

I only see one audio Data Block Collection in my EDID info, but it specifies 2-channel PCM at 32, 44, and 48kHz.

It would appear that the Intel drivers need to see a PCM mode.

I thought about this a little, and I don't think it would work the way you want in PDVD. PDVD sees the HDMI adapter as both an SPDIF device and a multi-channel device, so you would need to go into the sound applet and change the default audio device to switch between Intel HDMI and Realtek SPDIF.

On the other hand, TheaterTek lets you select the output mode and the sound device. Therefore, you could select HDMI audio as your default device in the sound applet, and in TheaterTek, select SPDIF and the Realtek sound device. Of course, TheaterTek does not play Blu-ray and HD DVD, so this is not what you are looking for.

Hi, just wondering if anyone has approx figures of CPU usage during MPEG2 playback with an E8x00 CPU & G35 Mobo using IGP? Also, preferably with Vista SP1 so that HA is enabled for MPEG2 (I think I'm right in saying MPEG2 HA's not enalbed without SP1)

Thanks!

The portion we care about is:



Bit 6 of byte 03 (the first red byte) confirms that your TV supports basic audio.

The group of red bytes (15 07 50) specify that your TV supports 6-channel AC-3 sound at 32, 44, and 48 kHz. That is the only audio Data Block Collection that I see. As far as I can tell, your TV's EDID does not specify any PCM modes.

In contrast, here is the same data from my TV:



I only see one audio Data Block Collection in my EDID info, but it specifies 2-channel PCM at 32, 44, and 48kHz.

It would appear that the Intel drivers need to see a PCM mode.

-Dave

Dave, that you can tell that the Intel drivers need to see a PCM mode from those EDID numbers must be some type of black magic. I hope there's a cure that works for my LG TV - do you think there's a work-around, or am I just SOL?l

I monitor the thread for the TV (LG 42lc2d) and there's nothing about any new firmware there so I hope that's not the problem because this is the TV one of the HTPC's is for & it doesn't appear to have any f/w updates available.

Ah interesting, I have an LG 42LB5D. There is a firmware update for mine, I'll try flashing it this weekend. Here is my EDID info:

Yeah, me too. It is pretty disappointing. I have a Toshiba HD-A2 that decodes and passes mulitchannel PCM to this receiver over HDMI with no trouble. However, the Asus board just won't do it. I can't upgrade the firmware online because it is not offered for download. I don't know if I have any other options. The system has 7.1 analog inputs and I will be using those until Intel upgrades their driver (if that will even "fix" this.)

Works great having a PS3 sending 8ch PCM to my Denon 2807 over HDMI as well. Haven't tried with the HTPC yet (only waiting for the E8400) but will as soon as possible, though I think I saw someone else in this thread that had problems with a P5E-VM HDMI and a 2807. Well, I guess I'll find out soon...

Shouldn't it be possible to send 5.1 over spdif too?

Yep. I have done that with no trouble.

I just hooked up the analog 8 channel to my denon and I don't know if it is crappy cables or what but I get a horrible buzzing sound in all speakers no matter what input I am using. Anyone have any ideas?

Well, to be honest, I am not a 100% certain that the Intel drivers need to see PCM. I just concluded that based on the fact that your TV's EDID info only has AC/3 and my TV only has PCM. However, I think this makes sense. In the HDMI audio control panel applet, it appears that you need to use PCM in shared mode, so if an output device does not advertise PCM via EDID, the Intel drivers don't know what to do.

I had to read the Wikipedia article many times to figure out how to decode the EDID. The article could be written a little better.

I have not yet decoded the EDID info from my Onkyo 905. However, I can tell that there is a lot more data there. Since the 905 creates a hybrid EDID block based on the video capabilities of the TV and it's own audio capabilities, I would assume that the extra EDID info from the 905 is reporting additional audio capabilities.

Is the AMP and the HTPC fed from the very same wall socket?

If yes - then I don't know (guess you have already tried adjusting the output level)

If no - try that.

Nope, they are plugged into different wall outlets. I will try moving and see what happens.

Probably ground loop feedback. Is the receiver and PC on the same outlet? You might be able to isolate it by plugging the devices into surge suppressors. If not you may have to isolate which cables are causing the ground loop and put a isolation transformer in line.

I have this problem with my subwoofer and had to put an isolation transformer on that coax link to remove the hum from all the speakers.

I got it from BB in the car audio section.

Nice work Dave! Archibael will be really proud

Just to let you know, the new version of DTDCalc is now in "beta" (that's what I call asking Archi to have a look at it ).

The main difference directly relates to the EDID issue you're addressing here. There is a new tab called "Interpret EDID". Simply paste the EDID information from your report into the available box, click "Interpret" and there you have it. All information relating to the capabilities/characteristics of your TV/AVR will be displayed with the DTD's extracted ready for editing as well.

Hopefully it will make life even umm...easier?

If you want to try the Beta, PM me and I'll give you the download details.

That will great diagnostic tool for people having problems. I think that Gris was pulling his hair out trying to figure out why he could not get HDMI audio to work. Your "Interpret EDID" feature should make it a lot easier for people to figure out that they have an EDID issue. Manually decoding the EDID info is a real pain.

Now that I know this feature is coming soon, I won't bother trying to manually figure out the EDID for my 905, I'll just use DTD Calc!

Hi Gris,

Not black magic but a firm grasp of Hex to binary conversion (so nearly black magic ).

I very much doubt that the TV only accept AC-3 audio (especially from your evidence). I've checked the EDID (admittedly using the DTDCalc beta only rather than the manual method) and get the same results as Dave. If this is the case I think you need to take this up with LG rather than Intel. From what I can gather, Intel are unlikely to start ignoring EDID information any time soon and strictly speaking, the TV shouldn't advertiser something it's not capable of doing. Even if it can decode AC-3it's unlikely to be at the expense of 2-channel PCM.

Perhaps they can offer you a firmware update?
