Windows 7
No HDMI Audio

I figured it out! You have to uninstall the IDT driver, restart with the computer plugged into the monitor via the HDMI cable. It will auto-install the correct driver. Then you have to go to the device in your sound menu and set it as a default device. It was really simple in the end!

Similar problem solved

Hi, I posted this in msn answers bc I found a solution for my particular issue which seems to yours:

I lost audio on the HDMI input of my TV/Monitor, all drivers (nvidia WHQL 258,96, realtek sound were up-to-date) and this is the setup:

-OS: Windows 7
- Video card: Nvidia XFX GTS-250 connected to a 32LH70YR LG Full HD TV through a DVI to HDMI adapter cable.
- Audio: 3,5mm audio cable from one of the rear outputs of the motherboard integrated sound to the sound input of the TV.

The solution I found:
1.- HDMI integrates audio by default, so I disabled its audio feature like this:
a. On the clear desktop, right click then go to "NVIDIA Control Panel"
b. At Nvidia Control Panel, go to Display -> Change Resolution.
c. Select your desired resolution and make sure the HDMI-HDTV connector is set to "Audio disabled", this way the TV will use the audio coming from your sound card and not the default integrated in HDMI.

2.- If that didn't work inmediately, then you may have a program related to overclocking/temperature measurement. In my case I had running MSI Afterburner. CLOSE IT. Then try Enabling/disabling HDMI sound as explained in point 1.
- Don't forget to play a song or video, as well as checking your TV's volume and player volume before saying it didn't work.
- Also make sure the tv speakers are set as your default device under "Windows Control Panel -> Sound". You can even change the icon to a TV-like one.
- I did this with all devices on. I've read you need to turn on PC then TV, that's not true at least for me.

Good luck.

Windows 7 Pro & Vista Home Premium

You need to completely uninstall the video card drivers before updating.

Download Driver Sweeper

Now go to this page to update your chip drivers and NVidia drivers:

Windows 7 Professional x64
Everything on laptop shows there should be sound !

WW3 - I have the same problem you have described and apparently solved. Namely, I have video through the HDMI from my Vaio to my LCD (Sony), but no audio. I can see the levels moving in the volume mixer (For iTunes and Sony TV) but there is no sound. My laptop speakers are disabled and HDMI, which is the TV, is set to be the default in the control panel.
I have had my Vaio connected successfully to a Panasonic TV about a year ago and remember I had to reboot if I was to change my default speakers. However, if I change the default back to laptop, the sound plays without having to reboot.

I'm really stumped. Could you let me know how you fixed your problem?

Yep. All you have to do is get a stereo 3mm male to RCA female adapter and plug it into your line out jack on your laptop. Newer HDTVs also have a pc audio port. You might want to check to see if that is an option. If so you just need a stereo 3mm double male cable.

Windows 7 should recognize and you should be able to select the port. Line out is usually labeled with speakers and the audio driver you are using.

Windows 7 64bit
No Sound

I'm by no means a computer person. However I've beenusing my desktop with my HMDI tv 42" LG for about 6 months now without a problem. I've choosen to use the tv speakers over my computer speakers just for the sake of ease. Anyways everything was working fine until a couple days ago. For whatever reason I get no audio through the hdmi cable. My computer shows that the sound is working fine but I don't hear anything. If I change the audio to my computer speakers everything works fine. Switch it back to HDMI and nothing. All drivers are updated. I don't know what happened or how to fix it but it's really frustrating.

windows 7 Ultimate 32 bit

Windows 7: No sound in HDMI output using Recommended Realteck Drivers. Re-solved. I have a Sony Vaio VGN AR 61M Notebook. I upgraded from Vista to Windows 7 32 bit and had exactly the same problem. This Solution worked for me: 1: I Remove installed drivers from the sound card and delete them with the given option. 2: Re-start Windows. 3: Windows will recognize you have no drivers for your sound card and install its drivers, which work fine. I have HDMI Audio out to my LCD TV through the HDMI cable. Everything works fine. Hope this works for you.
