Onboard HDMI Won't Allow HD Audio & Video?
Apr 3, 2011
With Windows XP SP3 I was able to transmit audio which was digital and sometimes multi-channel to my Denon reciever through the HDMI output on my motherboard; I was also able to simultaneoulsy display my computer through that same HDMI connection through my Denon reciever and on to my my Toshibe LCD TV.But when I installed Windows 7 Ultimate 32bit the HDMI audio was very limited (only 16 bit 2-channel @ 48,000 Hz) and can only select it when the reciever is on (which makes sense, but it's anoying to have to go into sound properties and switch to HDMI if I started the computer before the reciever, I hate technology trying to pretend it knows what I want it to do, it should just be able to do what it's told.) Then, when I turn on the TV this message comes up (which I would see when I was using XP but it didn't change anything)An HDMI-to-DVI display connection has been detected. In order to hear audio on your HDMI based TV or display, you will need to have a seperate audio conecction from you computer sound outputs to your TV or audio equipment.However I'm not using the DVI at all I just want to use the HDMI into HDMI because that's the way it's supposed to work because HDMI is supposed to handle both and I shouldn't need to use another cord when I'm already using one that does both.And so then my sound no longer works but my computer shows on my TV.Whoopdee doo! why can't I have both. HDMI is supposed to support both and when computer/motherboard/OS manufacturers put these technologies on computers you'd think they should commit to applying them flawlessly the way they were intended to be used.I understand this may be a driver issue and I've tried many combinations of the newest & the just HDMI Realtek Driver as well as the Gigabyte mother board drivers and the appropriate ATI/Catalyst driver/downloads.

I have a nvidia gt 9600 video card, and want to dual monitor to my large screen tv to use media center to watch movies, go online, etc. The card has 2 dvi outs, one goes to my primary monitor, the other I have a dvi>hdmi cable>tv set up.
I know I do not get sound out of this video card, but can someone show me the proper card that I can get both audio and video out with using my hdmi cable to do this? The geeks at Best Buy seemed baffled when I asked them about a video card, and using just the hdmi cable to do what I wanted.....I do not want to run multiple cables, etc...

i've just built a htpc using some old bits from a gaming pc, but when streaming videos full screen the audio and video are very choppy, with the audio including crackling sounds. for example, if i watch a 1080p video on Internet, it works reasonably well (with the odd pop from the audio) but as the controls overlay (with the play, pause and video slider) slides away the video slows down and there is a lot of crackling from the audio. there is an even worse problem with bbc iplayer and skygo when watching on fullscreen as the entire time the video almost seems slowed down and the audio is very choppy. if however i watch a downloaded video fullscreen, there are absolutely no problems at all.i have only just build this pc so i believe all drivers are up to date. i'm using windows 7 and have therefore disabled aero to see if that helps (it helped slightly). the hardware is as follows:
cpu: core 2 duo e8400 at 3ghz
graphics card: nvidia gt 430
motherboard: gigabyte ga x48 ds4
ram: 4gb ocz reaperx
for my old gaming pc i used all the same parts apart from using a gtx 460 for the graphics. this was then set up exactly the same way as this new htpc (into a samsung tv via hdmi from the graphics card) and yet worked absolutely fine. so the only thing that has changed is the graphics card, but the gt 430 is supposed to be able to easily handle hd video and audio.

I have a Sony laptop with hdmi output.
I keep my hdmi plugged in as a watch dvd's everynight through media center, onto my 32" tv.
The thing is, the sound taskbar used to automatically switch from hdmi to the laptop's soundcard automatically. It doesn't any more. Basically, if I turn off the hdmi mode on my tv, it used to switch from hdmi sound output to laptop's card. When I activate hdmi again, it would automatically switch to hdmi output.
I'm using the nvidia provided drivers via windows update.

Here's my setup: Nvidia video card>HDMI out to Sony Home Theater System>HDMI out to Samsung HDTV. I use this to get 5.1 LPCM surround sound for video games. It worked fine until I did a firmware update on the Sony unit. Now, the HDMI audio is greyed out in Windows 7 audio playback options. Nvidia Control Panel sees the device as audio compatible, but Windows does not.Audio DOES work if I connect a different display (through the same system). I connected an Acer computer monitor and everything worked normally. It also works it I connect it directly to the Samsung TV. The Sony unit works on its own or with the Acer monitor connected. When the monitor is connected, Nvidia Control Panel sees the home theater system as Sony AV System and Audio Playback reports SonyAVSYSTEM. When the Samsung TV is plugged in, Nvidia CP sees the home theater system as Sony Digital Display and Windows audio just says the cable is unplugged (doesn't report anything). I'm getting picture with this setup, but I can't even select the audio option.
I'm going crazy at this point, I have Sony working on it from their end and Samsung insists it's not their fault. Is this a Windows problem? I find it strange that Nvidia CP can recognize the unit and marks it as audio-capable, but Windows says a cable is unplugged. I've tried all recent driver options for both Realtek and Nvidia (Betas and stable). All drivers work the same under different connections described above. That the system works normally unless PC>Theater>TV makes me think that this is a pretty specific breakdown in communication with HDMI!date:Sony representatives got back to me with the findings from their engineers. They insist that because my PS3 works on the setup, it must be an issue with my PC. Their best guess is that the devices are failing to handshake properly over the HDMI connection.

I'm trying to hook up my TV with my computer, and for the most part it's working. The video goes through and I get how to control it and everything. The only thing not working is the sound.
I'm using an HDMI to HDMI cable, and like I said the video is fine. Also, when the cable is plugged into my boyfriend's laptop, the sound comes out of the TV.
So this must mean the problem is with my computer specifically. Although, this computer is only a month old, so I wouldn't think anything is out of date.

Is anyone having a problem with their ALC658 chipset? I bought a motherboard that came out of a Compaq with that chipset and am having no luck using the Realtek drivers. No audio whatsoever.

I have a HTPC setup. PC includes an ASUS MB with on-board video and audio, including options for either separated analog 7.1 audio out or HDMI out (among other output options). Current setup routes Audio and Video via HDMI to Pioneer VSX-1020 A/V receiver, and routes video from there to HDTV via another HDMI cable. OS is Win7 Ultimate x64, w/SP1.
Exact model for mb is here: ASUS M4A88TD-V EVO/USB3 AM3
When I play audio files, the receiver can fake the signal into all 5 channels (I don't have a sub, so the .1 is not relevant here), so there's no issue of the receiver not accessing the available speakers.
The main issue is this: When I look into the Sound Control Panel, under Playback Devices, the active/default device is ATI HDMI Output. Also listed are Speakers (not plugged in), Realtek Digital Output and Realtek Digitial Output (Optical). I do not have any analog cables plugged in, nor do I have an S/PDIF (optical/coax) connected. The HDMI works, but only gives me the option of Stereo (2ch). When I go to the Configure screen for the ATI HDMI Output, I see a list of Audio Channels, but that list ONLY contains Stereo.

I am trying to get audio from my PC via HDMI into my Marantz NR1402 AV Amp and then into my panasonic plasma.the plasma is picking up the desktop (so the signal is going thru the amp ok but the amp is not receiving any sound. In the Nvidea Control panel Set up Digital Audio it recognises The marantz under HDMI but in the configure section "open windows sound setting" it only shows speakers (not plugged in) & Digital Audio (S/pdif) Default device (i am showing hidden & disconnected devices).I have opened the pc case and noticed that I have a two pin cable from the 9500gt going to the Spdif on motherboard & a cable running from the soundcard to the front sockets on the pc case.

I installed Windows 7 yesterday and at first I had no audio to my TV via the HDMI cable. I adjusted the settings via the sound icon on the taskbar, playback tab, changing whether the speakers or the Digital Output Device (HDMI), Sigmatel High Definition Audio Codec was the default. Eventually I got it to work.
Today, however it has stopped working again and no matter what changes I make, nothing works. When I right click on the playback device Digital Output Device (HDMI) and choose TEST, I get the message: Failed to play test tone. All sound comes through the laptop speakers.
I went to device manager and checked the driver for the codec and it was up to date.
When I was using Vista, to get the audio all I had to do was plug in the HDMI cable and the sound automatically went through the TV.
Does anyone have any ideas how to solve this?

i have an Alienware M17X R3 with an HDMI INPUT which i can plug my xbox 360 into and play it through my laptop monitor. Is there any software that will allow me to use the HDMI IN as the primary video input, in oppose to the actual desktop screen? i tried using a few free softwares in which it records the "HDMI IN ON" message that shows up, but when it goes away and when I see my dashboard, the recording software sees my desktop image. i do not have a capture card, nor do i want to use one. i simply want to use a software (if there is one) to capture the HDMI IN on my laptop.

I've been keeping an eye on these forums; I find that it provides the most succinct information regarding Windows 7.
I finally bit the bullet and made myself a HTPC running Win 7 RC 64-bit. The whole purpose was to play ripped DVDs (to VOBs) from my NAS, any downloaded shows (as AVI's) from my NAS, and hopefully BluRays via the BD-ROM (I have a PS3, so this was not the main reason).
It seems that I was able to get the first two objectives working without any work. All I had to do was install the latest Catalyst drivers.
However, I can't seem to get Cyberlink PowerDVD 9 Ultra (or Windows Media Center) to play BluRays with anything more than 'stereo.' I've tried to research the topic, but there's just too many acronyms flying around (PAP, AAC, AC3, etc) that reading forums is like greek!
From my understanding, I know I can't get the DD TrueHD (or DTS-MA) to work via HDMI. However, I THOUGHT I could at least have PowerDVD "convert" (is the proper word downsample?) the DD TrueHD to a 5.1 Multichannel audio.
Am I completely wrong? Is what I want even possible?

I have an Asus x83v laptop and recently upgraded from vista to 7. On vista when I plugged in the hdmi cable the audio and video would automatically go through the tv and back through the pc when unplugged (video would be displayed on both when plugged in). Now since I installed windows 7 only the video goes through automatically and the audio stays on the pc speakers unless i manually change the tv speakers to default in the control panel. How do I set it up to change automatically like it did in vista?

I recently connected my HDMI output from my LCD to my PC.I have Nvidia GTS 250. I looked around for some tutorials and solutions to my problem but non of them seem to work since they all say the same thing: set the HDMI as default in my audio settings. I tried but i couldn't do it because it wont let me. I open up Control Panel> Sound and I can't seem to find anything but my SPDIF. When I click on it, the "Set as default" button is not availble. I can't press it. when I right click on it.I had Nvidia Geforce 8400GS.Nothing. Then I updated to the latest drivers. NOTHING!So I installed my old GPU, Nvidia GTS 250 and also installed the latest drivers form their website and still nothing!I tried to remove and reinstall Realtek HD audio drivers and still nothing. When I right click my SPDIF option I see "test sound" and when I click it I can see the green audio thing goes up at the system tray.

The problem: Sound is working fine through my laptop speakers but when I connect it to the TV via HDMI cable the sound still comes through the laptop.
I was previously running Windows Vista Home Premium and it worked absolutely fine. As in, the sound came out of the television speakers when I connected the notebook to the TV. I recently upgraded to Windows 7 Home Premium and since then it does not work. I would appreciate if anyone could help me.
Right now the default sound output device is: Speakers/Headphones - SigmaTel High Definition Audio CODEC. The other two listed are Realtek Digital Output (Optical) - Realtek High Definition Audio and Digital Output Device (HDMI) - SigmaTel High Definition Audio CODEC.
When I try either of the other two sound does not work at all. With the Realtek one it seems to recognize the sound but I don't hear it anywhere and with the HDMI one, it doesn't work at all i.e. Fails to play test tone. I have installed all the latest drivers according to manufacturers.

I have a Sony VAIO VGN-AR390E laptop. It has a SigmaTel High Definition Audio device and an Nvidia 7600 GT. My HDMI audio doesn't work and I have tried for hours today to get it working again. It previously worked just fine in Windows Vista. I am connecting it to an Integra 7.8 receiver which has video pass through via HDMI to my Mitsubishi WD-73737 monitor. I have tried connecting straight through to my TV with no luck in the audio department, and also to someone else's TV with no luck in the audio department. However, a different laptop's HDMI audio worked just fine. The image is displayed correctly though.
Today I tried uninstalling my current nvidia drivers (195.62) from laptopvideo2go and installing 2 different sets of video drivers provided by Sony for my laptop that are a bit dated now. No luck. I uninstalled and re-installed the current audio drivers by Sony. No luck. I also tried the previous version of the audio drivers without joy too. I also installed the Intel chipset drivers too without luck. When I go to the control panel and click sound and properties, I am setting the HDMI/SPDIF output to default and disabling the speakers/headphones option.
The speaker icon in the taskbar shows the sound levels going up and down while playing material back- but I can never hear anything. I've tried the 44khz, 48 and 96 options, and Dolby Digital, DTS checked and unchecked and nothing makes a difference when I'm trying to test them. Everything used to work with my receiver except for the WMA Pro option. Now my receiver just says "No Audio Stream Detected" while I'm trying everything.
I did have the K-Lite Codec package installed but since deleted it. I also tried messing with the AC3 Filter- and also deleted. No luck there either. I've tried powering down and resetting all of my equipment many times. I'm out of options- any suggestions are very welcome!
