Lost HDMI Audio
Nov 29, 2009
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!

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 Although, this computer is only a month old, so I wouldn't think anything is out of date.

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.

My problem is that I my HTPC drops the HDMI connection when I exit media center.
When I am in 7MC I can play all my ripped DVDs, Blu-rays, and music. But when Media Center closes (or in window mode) the HDMI connection drops off. I can see the "No Signal" messeage in the Onkyo display as soon as 7MC closes, and it reconnects again when 7MC opens. I need the connection to say active so I can have sound with NetFlix (apparently it runs outside of media Center even though I launch it in 7MC).
why my HDMI connection is dependant on 7MC running?

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'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 happily been viewing movies etc from my laptop to my TV via an HDMI cable for the last 2 years. However, I installed Windows 7 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.

I went to device manager and checked the driver for the codec and it was up to date. I downloaded all available updates from Windows and my laptops software updates and just now re-installed my sound and video drivers but to no avail.
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.

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 am currently on windows 7 with a ati radeon hd 3600 graphics/audio card. When I plug it in to my home theatre through HDMI there is only a 2.0 sound configuration, there is no 5.1. My home theatre is a sony ht-sf470. It is 3 months old and it is capable of dts-hd 5.1. How can I configure the HDMI to 5.1.

I only have this problem with 7, so I know it is not a hardware related issue. I simply can not get any sound out of my graphics card (seemingly) through HDMI. I have my bios setup to play audio from it. I've followed what everyone else has done when using the search, I have zero success. It worked before using 7, so I am 100% confident that this is a 7 issue (because it still works on Ubuntu!).All drivers and software is up to date too.

After uploading newest drivers, scrubbing my clean install of various generic audio and video codecs, drivers, devices and tools, I had spend about 4 hours of my life trying to get audio to work using a device that worked under XP MCE 2005.
Enough being enough, I weighed the costs and purchased a Galaxy GeForce GT220
for about 90 bucks at that local big box store. Sure I could have saved about $20-30 driving about 30 minutes each way in winter wet weather. I wanted audio over my home theatre system and I wanted it now.
First I downloaded the newest drivers available, installed the card, ripped out the default drivers and installed the new set. Peace of mind, 7.1 sound, priceless. I'll use that other card in my office where the silence of a passive card will be more appreciated.

ok to uncomplicated things ive read thru the forums and could not find anything concrete on this problem of mine..
i have a gigabyte mobo/amd cpu w/onboard hdmi
my issue is sound switching right now as it stands, i need to manually switch on my pc between the HDMI audio as my main device and my PC speakers as my main device... on my laptops this is not a problem, it can automatically detect if hdmi is plugged in and switch sound over..
the main reason is its a slight pain to keep going over after a movie and switch over, nor do i want to disconnect a hdmi cable every time..
any suggestions how to automate this problem???

I upgraded to ultimate 7 64 bit.... I have ATI HDMI audio.
My laptop is using an external monitor which I am connected to via HDMI. This monitor has an audio output that goes to computer speakers.
Programs like itunes will play audio perfectly, however when I try to watch a dvd i get nothing but static sounds. I have used windows media player, and windvd... same static audio sounds.
*When my computer is not connected to the external monitor via hdmi, the sound works fine when playing a dvd and coming out of laptop speakers...

This is becoming a pain in the ass. I am using HDMI through my AMD 6850 to my LG TV for audio and video. It has been working fine(no audio problems) for about a year.Just recently, with no hardware or related software change I can think of, now, if I switch the input on my TV(for example go to HDMI1 to watch TV and then back to the PC) there is no audio. It becomes disconnected, I have reinstalled and tried using the AMD HDMI driver and the Realtek(my chipset) HDMI driver. When I switch inputs, sound manager shows HDMI as "not plugged in". The only way to fix it is to unplug the cable and plug it back in while staying on the PC HDMI input

After upgrade from Vista 64 to Win7 the internal speaker work, as do all audio jacks (both speaker and microphone). But when I connect my laptop to my HDTV via HDMI, I get no sound throughput. Also I can not see in playback devices the HDMI audio option.
I already updated the SigmaTel Audio Driver and the Intel GM965 Express Chipset Video Driver and still the problem.

I have an Acer GD235HZ monitor with HDMI input and an audio output jack. I've tried reinstalling and uninstalling and new installing everything to do with the drivers available for video card and monitor. Video card is GTX 470 and does have the ability to output sound through HDMI. I can't figure this one out, I need help! I'm using Windows 7 service pack 1 and have all drivers up to date. Oh, and the video output works perfectly!Also, yes I've tried different cables and have double checked that my headphones work that I'm plugging into the output jack from monitor!

I've got a bit of a problem with my audio with my new installation of Windows 7. Previously I had Vista installed, and had no problems with my Realtek HD audio. Installed Windows 7 everything looked good, then realized my Sony A/V receiver model SA-WCT100 was not outputting my movie collection in surround 5.1 like it use to using Vista.
I figured, that�s cool, probably need to install ac3filter_1_51a, I had to in Vista, and it worked a treat when I enabled SPDIF pass through. I guess I should mention I�m using HDMI all the way through, from my PC to the receiver, from the receiver to the LCD. Well, that didn't fix it, everything still plays in stereo. After scratching my head and clicking here and there, I finally found a little tab in the sound settings of my Realtek HDMI setting called 'Custom'.
I selected it, it said to enable AC3, DTS, etc click this box will require a restart. I said awesome, sounds like just what I need. I clicked, and rebooted. I went into WMC, and setup my audio wizard again, and selected 5.1, and tested, and this time it reported 5.1 on my Sony receiver as before it only showed 2 channels (Stereo). I played some of my DVD rips, and bam my DVD rips were playing surround sound again.
I was like that was easy enough. I went to test my Blu-Ray rips that I had converted to WMV HD using TMPGEnc Xpress 4.0, and the video started to play, and I was like, wheres the damn sound. I noticed on the receiver, it didn't report anything for sound. I had no idea what was going on. My surround sound was finally working for everything, but my WMV HD videos had no sound output. I mean I can't even get stereo or anything out of them now. At least before the WMV played in stereo, now I can't hear anything.
Please someone tell me what could be the problem, I don't know what else to try. I don't want to have to revert back to stereo, and disable the magic box under custom in my sound setting.
I have downloaded the latest Realtek drivers form Realtek, version 2.35 for the ATI HDMI audio, and the Digital Audio. I also have the latest drivers for my integrated Radeon 3200 graphics card. I read that sometimes a high resolution can affect the audio, so I lowered my resolution from 1080p, and that didn't help, which I figured it wouldn't.

When playing back two channel pcm music on my diy home theater computer, the output begins to progressively contain random static as additional tracks are played. The operating system is windows 7 64 bit. There are no issues with 5.1 audio as it is always clean.My motherboard is an Asrock H67M and my processor is an i3-2100. The computer is connected to a Yamaha receiver via an HDMI cable.Video from the i3-2100 is outstanding on my 52" Sony TV. I am using the on board Intel display audio device as this appears to be the only way to transmit digital audio output to the receiver via HDMI. The only way to get clean sound when the static becomes unbearable is to turn the computer off and reboot. I'm not sure it matters, but the computer does contain a TV card.
