problem with surround HDMI-Yamaha

If stereo is the only option, sounds like it may be an EDID issue.

No, it's not an EDID issue, everything is working normal, unless he means "no 5.1 sound" = "no DD/DTS".

I have the exact same issue with a Gigabyte mobo with HD3200 onboard graphics. Mine worked perfectly before replacing harddrive and reinstallin 7 x64 ultimate. Previously stereo, quadrophonics and 5.1 were in the dropdown box. Now only stereo is an option. It will not send 5.1 to my Yamaha RX-V667. I would love to find a fix as this is driving me crazy. Help!!

Hmm, are you sending audio from HD 3200 over HDMI? Then the only supported audio formats are

- Stereo PCM
- Dolby Digital
- DTS

5.1/7.1 LPCM is supported only by discrete graphics HD 4xxx or later, and the latest Llano's integrated GPU.

Yes, over HDMI. I've used this with an Onkyo ts-xr606 and also with th current Yamaha rx-v667. I've been using the system for 3 1/2 yrs now. I could look at the front of the receiver and see which is being sent to it. In media center setup it will ask which setup you have and run through all 6 speakers. Now it will only do the 2 fronts and the sub. I know for a fact this card will do as I've stated. Why, however it now doesn't work, is a totally different question. I don't mean to sound like a know it all, but this I'm sure of. I'm wondering if it's a Yamaha issue. I used to see the Onkyo in the display menu, but now I see the tv and not the receiver.

there is no difference between the digital audio caapabilities of hdmi and spdif optical/coaxial on that motherboard unfortunately.

Minbomb, what do you mean?

According to Gigabyte this mobo is capable of 7.1 with full HDMI support of compressed and uncompressed audio and video. The question isn't whether or not it can do it, it's why isn't it doing it now. The board is also HDCP compliant but shows no support in the properties window.

The description on the page you cited is wrong or at least very ambiguous. Every 780G mb+HDMI AVR user knows that HD 3200 supports only stereo PCM, DD and DTS for a fact (except for you ). The audio formats supported by S/PDIF are stereo PCM, DD and DTS, the same as HD 3200/4200/4250/4290 iGPU (and HD 2xxx/3xxx dGPU). That's what MlNDBOMB means.

If you want multichannel LPCM over HDMI, adding a discrete graphics is a quick fix (or upgrade CPU/mb/memory to either AMD Lano APU or Intel SNB).

So, if I installed my son's ATI 4350 into this machine, it should work? I'm not trying to argue. Going with what the description you gave shows, should media center test tone all 6 speakers in it's setup with my current setup?

Yes, HD 4350 supports multichannel LPCM over HDMI. As TX-SR606 and RX-V667 both support TrueHD/DTS-HD, you'd better buy a HD 6xxx or GT 4xx/5xx graphics card.

Very good. 2 more questions. In my son's HDMI properties, it only showed stereo. Is that right? Also, ATI or NVidia? ATI CCC has that issue with HDMI reverting to DVI turning tv back on. I have to use CCC 9.12 to avoid this. It looks like that CCC is good up to HD5900. Any thoughts? Thanks

What display (or AVR+display) is your son's system connected to? HD 4350 supports DD, DTS and up to 8 ch LPCM, but the actual available formats depends on EDID of the display. For example, if it is connected to a PC monitor with HDMI and built-in stereo speakers, then Windows sound control panel will show only stereo speakers in "Speaker Setup".

The current Catalyst driver/control center version is 11.10 (i.e. 2011 October version). Yes, 9.12 (2009 December, almost two years old) supports 5900, but in general you should try a newer one.

LCD tv. That was my question on my system. Should the Yamaha show up? Does the PC use EDID with audio included?

So, with 11.1 that would leave me with the same DVI issue. Does NVidia have this issue also?

If the PC with HD 4350 is directly connected to TV, then the available audio format is almost always only stereo PCM. Some TV supports DD via HDMI in, but this is rare. EDID includes audio information.

What's "DVI issue"?

When tv is turned off then back on, the HDMI reverts back to DVI. Like I was saying earlier, my Onkyo used to show up in the display properties but the Yamaha doesn't. That makes me wonder if the Yamaha info isn't making it to the PC. I should get DD and DTS. I get nothing but stereo. That was what my original thought was and maybe not explained correctly.

Make sure that you have the Yamaha's HDMI audio out set to "AMP" and not "TV"

Checked last night, AMP 'on' TV 'off'. I've seen other posts about editing the EDID. Is this the best bet? I don't have problem putting in a 'better' video card but I think it will still come back to this.

I have yet to see a Yamaha that required an EDID override for audio. Try stopping and disabling the "AMD External Events Utility" service. The name may vary a little depending on driver version. Also, what is listed as your display panel in CCC?

My display is listed as my TV in CCC. Where am I looking for the "AMD External Events Utility"? I'm glad to hear that Yamaha has been good in this aspect. I bought after reading multiple forums saying how it was.

Found the "AMD External Events Utility". Will disable when I get home. Should I reboot after disabling?

No need to reboot.

I have 2 Yamaha amplifiers and I never needed the override for the 5xxx or 6xxx cards. The reason EDID overrides are needed (for audio) is because of missing or misconfigured audio blocks in the EDID. Yamaha's do not have the issue.

I tried the disabled as directed, no change. I attached my wife's laptop via HDMI with HD4250 onboard. I had the same results. From what I saw on ATI sight that should have yielded a minimum of 5.1. In media center setup, it would only do front speaker and sub just like my HTPC. Any thoughts? Please?

Right click on the speaker icon in the system tray select 'Playback devices'.

Double click on the ATI HDMI Audio.

Under 'Supported Formats' you should have:

AAC
DTS Audio
Dolby Digital
Microsoft WMA Pro Audio

If not, under the 'Custom' tab there is a check-box 'Allow AC3/DTS/WMA output.(Reboot required)' make sure it is checked.

Another thing I found is if you have the Realtek drivers installed. The Catalyst drivers will not give you the option of installing the audio drivers. It won't even show in the list. You need to go to the device manager and right click the HDMI Audio and select Uninstall. Making sure to check the 'Delete the driver software for this device'. then install the Catalyst drivers.

This is only available in XP, not Vista/Win7.

@ tiggerdevil, it sounds like you have the native Microsoft driver loaded. Can you confirm that?

If you mean 5.1 "LPCM", HD 4250 does not support it. 5.1 only via DD/DTS. Again every user knows that for a fact.

I had similar issues when I had the Yamaha RX-A800. On your Yamaha receiver under HDMI settings, try setting ARC (Audio Return Channel) to Off and see if it makes any difference.

Vladd, I have the ATI HDMI driver installed. I'm not sure version or release date. I've changed it so many times. Supported formats that show up is only DD.


Renethx, sorry if that was misstated and required attitude. I simply mean that it is only 2 channel regardless of source type. I tried with 2 different movies with known DD playback. Likewise MC setup won't test tone rear speakers.

big poppa pump, I checked that. The only other thing that came to mind is that when the HDD was changed the receiver was completely removed, all wire and speakers, and reinstalled. I wonder if doing master reset of receiver is worth trying. Right now I'm game for anything.

Thanks for the ideas.

That's odd I am running Windows 7 64 bit and that option is there for me.

I know when I was trying different drivers, I did have that once. Couldn't tell you which driver. What driver number is that?
