Hi,
do you have installed the latest Realtek HDMI Audio driver for ATI ? You can get those drivers on Realtek website

Hi Michael,

Thanks for response. No, the HDMI driver installed is the latest version that comes with the AMD/ATI driver set. These override the Realtek installation when you install the AMD/ATI Catalyst suite. I would expect the ATI driver is more appropriate given that the audio is passsing thru the video card output. Anyway, that's what shows up in my audio listing. I don't use the other Realtek on-board sound features (ie. the SPDIF and analog), although they're installed.

Dante.

I would give the Realtek driver a try....

Michael, thanks for the suggestion but I ran into the following:

I downloaded and installed the REaltek HDMI driver (now at 255) and installed it. It overrides the AMD/ATI HDMI driver successfully (by the way, this only works if you already have the ATI HDMI driver already installed - if you don't this installation fails). I could verify that it was installed and thru the sound control panel and I could set up 5.1 and test the sound coming into my receiver successfully.

When I start POWERDVD9 and try to play a disc with a DTS HD-Master audio track, I now get the additional option presented which is called "NON-DECODED HD AUDIO TO EXTERNAL DEVICE" which previously did not show up. When I choose this however, I get no sound coming out at all. If I revert back to PCM DECODED by POWERDVD then I get sound again.

This is amazing to me that none of these configurations where everything seems to be set up correctly simply don't work.

Not sure where to go next.

Hi,

what do you mean with

I could set up 5.1

I meant that in the Windows7 sound control panel I could choose the 5.1 speaker option on the "Realtek HDMI Output" choice and could produce sound going to the receiver. That tells me the driver is installed and working. I do that test anytime I make a change downstream from PowerDVD to ensure I still have multi-channel sound selected and working.

Just to add more info here. I've tried some other permutations.

I can now reproduce this same problem when I change video cards to a new EVGA/NVIDIA GT 430 card. This card is documented on NVIDIA site to support HDMI 1.4a. I loaded the latest version of the video driver and associated HDMI driver from NVIDIA (260.99) I can verify that the card supports the bitstream audio formats thru Windows Sound Panel and send audio output to 5.1 channels thru it as well. When I point PowerDVD9 to the HDMI audio I get the same results as above with the ATI 5000 series card combined with Realtek HDMI audio driver. With the NVIDIA card I can see and choose the HDMI output, select "non-decoded HD audio" thru PowerDVD9 and still have no audio thru that option. When I choose PCM decoded by POWERDVD I can get PCM audio stream to receiver.

This all tells me that the video card choice and HDaudio driver whether Realtek or NVIDIA thru HDMI do not have a bearing on this. There is an issue with POWERDVD9/10 (I tried both and got the same result) sensing the HD audio device and sending the right stream to it.

This may not help at all and probably even sounds stupid but if your not plugged into HDMI1 on your receiver give it a try. I have an Onkyo TX-SR706 and couldn't play a Blu-ray or DVD even without it being on the first port. Doesn't make any sense, you would think all the HDMI inputs would be the same but obviously not.

Thanks for the suggestion but I am using port 1 for this test. I've actually tried several of them. I have 6 in total to choose from and all exhibit the same problem unfortunately. I also made sure that the default programming on receiver is set to accept any kind of audio sent to it but to no avail.

Hi techguy I've had a few issues with ATI audio in the past some of the
resolutions have been

1) Use the Realtek driver (when audio via the ATI card was in it's infancy , I rebuild my PC last weekend and used the new CCC manager and 10.12 without any issue)

2) Playback is via a TV so in the past I've had to make sure I use an HDTV resolution; if your output is a TV try that

3) On Windows 7 (and Vista I think) going into audio devices, selecting ATI HDMI, properties, making sure that DTS-HD and DD-HD are supported formats. Also in the past I've had to change the default sampling rate (also in properties/advanced) from CD 44khz to 24bit 96000Hz studio quality or above.

My connection is ATI 5670 1Gb DDR5 HDMI -> Onkyo TX-SR708 AV amp -> Samsung C8000 TV (HDMI)

HI Tech81. Thanks for those suggestions. I had already tried most of those and thought I'd tried just about every permutation, however your suggestion # 2 actually helped to give me a clue.

It turns out that even though my display adapter was set to 1080P (1920 x 1080) thru the HDMI connection, the display driver defaults to the pc configuration and you have to go out of your way to add the 1080P HDMI choice in the output of AMD/ATI's video control panel. This is so obscure and not obvious. Once I did that, I was then able to select thru PowerDVD, the "NON-DECODED HD AUDIO to external device" and actually got the HD audio stream to my receiver. I should add that this only worked with the AMD/ATI 5000 series card (with driver 10.12) combined with the Realtek HDMI Audio Driver (255). The AMD/ATI HDMI audio driver included does NOT work in passing the HD audio bitstream out, however the Realtek one does. This means you have to install the Realtek HDMI audio driver after the AMD/ATI drivers are installed to override. This was already noted in prior suggestion from Michael of Cyberlink but wanted to make sure it was understood here as well.

I think it's kind of ridiculous that you have to choose an obscure option in the AMD/ATI CCC control panel to make this work. What this means is that as long as you're working with a display device that has a native 1080P resolution you're fine. Usually I connect to my JVC D-ILA 1080 projector so this is not a problem. When I connect my LCD computer panel which is a Dell 2709W model with resolution of 1920 x 1200, I have to downgrade the resolution to 1080P as noted above to make the HD audio stream work. It is beyond me to understand why the video stream configuration is connected at all to the audio stream. As far as I'm concerned these 2 should be separate configurable items.

This may be digressing a bit from the original issue, but I had an NVIDIA GT 430 card on hand, so tried it as well with my config. I loaded the latest drivers from NVIDIA site (260.99) and tested the same thing as above. With this card, POWERDVD9 will NOT pass thru the DD HD or DTS HD bistream audio and the options for NON-DECODED HD AUDIO is not presented at all. When using POWERDVD10 however (I downloaded the trial version), this does work. I think Cyberllink should fix this as POWERDVD9 should be able to use either AMD/ATI or NVIDIA chipsets for this as noted on the supported hardware list.

Note to Cyberlink is that all this should be better described on the web site info for hardware compatability and configurations. I'm glad I found something that worked, but I should not have had to spend countless hours trying this out the hard way. This also means that AMD/ATI should fix their HDMI audio driver as well and not force us to install a third-party driver (Realtek) to make it work.

Sorry for the long-winded message here, but given the # of people having this same issue that I've seen in the forum, I thought this might help others.

Thanks all for the suggestions.

I have the same problem, and I am still not able to get it to work. The HD audio output selection is not available from within PowerDVD, even if the movie is playing.

The only screen connected is my Sony TV, native at 1080p, so I do not the issue mentioned in the previous post should apply to me.

I have tried with the AMD HDMI driver as well as the Realtek driver - no difference. However, I found so many different drivers on the Realtek homepage, maybe I picked the wrong one.

Anyone?

My setup:
Win7 Ultimate 32 bit
Sapphire 5450 1GB DDR3
AVR: Yamaha RX-V1900
TV: Sony 52W4500

Deville,

You have a video card that I know works as I have one of those as well and got it to work for me.

The Realtek Audio driver you want is on the REaltek Web site under High Definition Audio Codecs and it's called 'ATI HDMI AUDIO DEVICE'. Current version is R2.55 and it's about 20 MB to download.

The Realtek audio driver must be installed after you install the ATI Video/Audio drivers which include the CAtalyst Control Center (ie. the complete suite).

Once installed, in the Windows sound panel, you would need to choose the 5.1 or 7.1 channel for speaker selection and apply that.

You also have to go into the AMD/ATI Catalyst Control Center (the icon should be in the right hand side of the task bar). Driver version 10.12 is current and worked for me. Inside this panel, you have to go into Desktops and Displays and you see your monitor/lcd display, choose HDTV support, add 1080p60 format to the display manager and apply, then select 1080p60standard at bottom of that screen and choose apply format there as well.

Once you do all this, Cyberlink should present to you the additional audio selection in the Audio tab. This only works after you start playing the movie (the first time you do it). The option is not visible until after you start the movie. A strange quirk of PowerDVD.

Also ensure that your receiver is capable of receiving an HDMI 1.3 or 1.4 as a standard to be able to process the latest audio streams and set it to any audio so that it adjusts to whatever comes to it.

As I noted in my previous message, a lot of these steps should not be necessary but such is the quality of software these days. Everything is about speed to market vs quality and ease of use.

Good luck.

techguy,

thanks for your help, it is much appreciated.
Unfortunately, it still does not work. I did exactly as described, except I used Catalyst 11.1, which is just out. But now I cannot even select HDMI in Speaker Environment, only Headphone, and 2, 4, 6, or 8 Speakers. In th Output mode I can only choose between No Effect, Dolby ProLogic, and TrueTheater Surround. I still get sound, but certainly no HD sound.

The only Playback device listed in the Windows sound panel is Speakers - ATI HDMI Audio.

I should also mention that my motherboard has onboard sound and video, the NVIDIA 9400. I purchased the ATI 5450 only for HD sound. Anyway, in the BIOS I disabled these diveces; onboard graphics, onboard HDMI, and onboard audio device. Is this correct?

In PowerDVD it is possible to display signal data in the upper right corner, see attached image. This shows Dolby TrueHD 5.1, but my AVR does not light up so I guess this is the signal from the disc into PowerDVD.

Increasingly frustrated.....

Deville,

Seems that you're experiencing a lot of the same issues I found during my experience with all this.

Given what you've told me, it would seem you've managed to successfully install the Realtek HDMI driver for ATI on top of the ATI driver however I wonder if the video card is actually seeing your receiver for audio. In the Windows sound panel, you should choose the HDMI output as default and it should show as enabled with a green checkmark. This might seem like an obvious question but make sure that you've connected the HDMI cable to the video card and not to the on-board HDMI slot. HDMI should show up as a choice on the POWERDVD menu of audio choices in all cases if HDMI audio is installed and enabled.

It doesn't matter if you disable the on-board video in the bios as long as the bios is set to choose the PEG (PCI-Express Graphics) selection as the default which overrides the on-board video when present.

In the attachment you sent, it clearly shows you've tried to choose Dolby TrueHD 5.1 as your audio source on your disc, however the bit rate is too low (should be > 9,000Kbps) and therefore it's showing that POWERDVD is downsampling the audio output since it hasn't found the HDMI connection yet.

I know your video card should work for HDMI as I mentioned I've used one successfully. I haven't tried the new ATI drivers yet but based on my experience that shouldn't make a difference once you use the Realtek audio driver.

techguy,

the HDMI cable is in the right socket (I checked ), and the HDMI is set as the default playback device. In fact it is the ONLY playback device, since I have disabled all motherboard devices. See attachment. Now, since it says speakers in the first line, and your hint that the video card sees my AVR prompted me to do a test:

I connected a computer monitor to the DVI output of the video card, and disconnected the HDMI cable going to the AVR. Guess what, the playback device disappeared from the Sound panel. Nothing there. Still visible under Sound, video and game controllers in the Windows Device Manager, but not in the Sound panel. This, I guess, indicates that the Realtek HDMI driver is NOT correctly installed.

I tried installing the Realtek driver on top of the AMD driver, and I tried deinstalling the the AMD driver before installing the Realtek driver, but no difference. (the latter is, as you mentioned above, not possible unless you restart between removal of AMD driver and installation of Realtek driver

It appears that the Realtek driver does not see the video card HDMI sound device.

techguy, I am very sorry for bothering you this much, but....

Deville,

Running out of suggestions for you.

What you described in your last message is normal behaviour. As soon as you disconnect the HDMI cable from your card, the sound driver will automatically disable that port. When you connect a DVI device the sound is not transferred thru that connection as DVI doesn't carry sound. That's all normal and it means your REaltek HDMI driver was working.

If I were to guess, your POWERDVD installation (not sure which version you use - only POWERDVD 9 Ultra and 10 ULtra support HDMI audio) may need to be re-done. If you do try that, I would make sure that the HDMI cable is connected and the HDMI connection active while you do so.

Good luck.

techguy,

thanks, I appreciate your help.

I have PowerDVD 9 Ultra, upgraded to 10 Ultra. I'll try to reinstall that, as you suggest.

Thanks.

I formatted the hard drive, and started from scrach with Win 7 (and all win updates), the motherboard chipset drivers, full Catalyst 10.12, Realtek HDMI on top of that (not deinstalling AMD HMDI first), PowerDVD 10 Ultra trial (to bypass any issues with my PDVD 9 + 10 upgrade) - and voila! TrueHD lighting up on my receiver. )

For all my other media I use J River Media Center, and AnyDVD HD, AutoHotkey, CCCP codec pack, CoreAVC codec for H264, and ReClock. Now I need to get all of that back....

Anyone who knows if any of this will interfere with HD sound over HDMI?

techguy,
thanks for your patience with me.
