Solved No sound via HDMI to ASUS Monitor

No sound via HDMI to ASUS Monitor [SOLVED]

I've enjoyed a lot of the useful information from you all on this forum. My problem is that when I connect my Acer Aspire 5810T Laptop to my Asus Monitor MT276 via HDMI, I get video on my Asus but no sound through its speakers. I'm getting sound through my laptop though.

I'm unable to see the HDMI sound icon when I use "Manage Audio Devices" even though I checked to show disabled and disconnected devices. I think it may be because of my graphics or sound card (which I've tried updating via device manager but still no luck).

My system specs are to the right and if you require any other information let me know. Any suggestions on how I can get sound through the monitor's speakers?

[SOLVED]

I now get sound and video via HDMI through my Asus monitor. The way I got it to work was by updated my chipset driver to an older version.

Steps I took:
1) Go to Device Manager
2) Open Display Adapters and right click and select Update Driver Software
3) Select Browse my computer for driver software
4) Select Let me pick from a list of device drivers on my computer
5) I then was given a list of drivers and selected the oldest version (2/26/09)

I restarted my computer and plugged in the HDMI and the HDMI icon magically showed up when I went into Playback Devices.

I have updated the OP to show my solution. Thank you all for your help. You guys have a very good community here.

Go to the Control Panel/Hardware and Sound and finally the Sound panel. If you have HDMI Audio, there will be an icon for this. Set this as the default playback device and that should get you HDMI Audio.

As I stated in the first post, I have no HDMI Audio icon when I go into sound devices. I made sure to show disabled and disconnected devices. I only see the Speakers and Realtek icons.

It has to be the Video card either does not support audio or has to have some external connection to get the audio. I don't have any info on the Intel HD Video.

Ok I could really use some info on Intel HD Video. Anyone with some knowledge on this?

If it has HDMI - it supports video/sound. I'm thinking driver or configuration on this one.

Can you send me a link to your video card / onboard stats?

Thanks for the reply brady. Here is a link to my video card specs from GPU-Z: http://gpuz.techpowerup.com/10/12/30/ez4.png

Again my laptop is a Acer Aspire Timeline AS5810TZ-4274. I attached my DXDIAG info of my computer specs. If you need any more info please let me know.

This worked for me

Hello

I had intermittent detection of the HDMI in "Control Panel/Sound", and eventually no detection (the following solution may also work for those who were never able to obtain a signal at all). For me updating the audio driver fixed the problem. You can update the audio and video drivers by following the steps below (found these steps at Microsoft website). My computer is only 6 months old, but still needed the drivers updated. No special system setting are required as written in previous posts, if the driver is the problem. I was also extremely frustrated with the ongoing problem and hope the driver updates work for you. Good luck!

Open Device Manager by clicking the Start button

, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.*

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
In Device Manager, locate the device you want to update, and then double-click the device name.
Click sound video and gaming controller
Open each audio controller in sound video and gaming (one at a time) and update by Clicking the Driver tab, and then click Update Driver and follow the instructions.

Thanks Rodney. I tried updating the devices using your method and windows said that they are both up to date. Still no sound through my monitor when connected via HDMI. Any other suggestions?

Sorry to hear it did not work (already update)

Not sure what you have done thus far. As far as settings go; in control panel/sound, is HDMI output recognized (is it there)? If so, make sure it is set as default device (by right clicking on it). You could also try unplugging and plugging back in the HDMI cable while the TV and PC are both turned on (this may allow the PC to recognize TV). I am not a super-tech-type, so this is about all i have for you at this point. Good luck

Assuming that dxdiag log is today's, you don't have the sound driver installed. At the moment it is running on the default Windows driver, which will provide basic audio but no advanced/extra features such as HDMI audio. Start with downloading and installing the latest Realtek HD audio driver,

and then see if the options shows up.

Still no luck. I downloaded and installed the "Vista, Windows7 Driver (32/64bits) Driver only (Executable file)", restarted and installed the driver twice, and still no option for HDMI when I look at Playback Devices (I have checked to show disabled and disconnected devices).

Perhaps I did not install it correctly? Do I need to download the "ATI HDMI Audio Device" driver too?

Here is my DXDiag after I installed the new driver.

Do I need to download the "ATI HDMI Audio Device" driver too?

No as from what I can see that model laptop came with either/or ATI or Intel for the video, and there is nothing in your dxdiag log that would indicate that it has the ATI.

May not make any difference but go here,

Acer Support - Drivers & Download

and get the chipset driver for it. From the looks of the log it appears that pretty much all chipset related drivers are using the Windows defaults. It could be that it will take the proper chipset driver for it to show up, as for a lot of things the Windows default drivers are enough to get things up and running but takes the proper drivers for things to work as they should.

I visited the site and downloaded and installed the chipset pictured here. It seemed to have no effect. When I visit Intel's website for information on the driver it tells me that the Mobile Intel(R) 4 Series Express Chipset Family is "A customized computer manufacturer driver is installed on your computer. The Intel Driver Update Utility is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues. Contact your computer manufacturer for the latest driver for your computer. "

So is there any driver on the Acer site that I should download that could make a difference and stop the drivers from using the Windows defaults? I've also upload my new DXDiag log.

Try connecting your HDMI laptop to a different HDMI device, like a TV or a friends TV if you don't have an HDMI TV. Not all HDMI ports are alike.

Tried hooking it up to a another TV with no luck unfortunately. The icon still did not appear. I'm assuming this is happening because I upgraded from Vista to Windows 7?

I am at a loss on this one. I assume it is a falty driver. My home video card with HDMI used the drivers from the Video driver download to install both the HDMI video and the audio. ?? Maybe send an email to the vendor of the drivers asking for help ?? Sorry I cannot be more help. -WS

According to the DxDiag, your sound device vendor is 10EC which is Realtek,
so it's ok to install the Realtek HD audio driver.
However, it doesn't enable HDMI sound.

According to the DxDiag, your display device vendor is 8086 which is Intel.
So you should have the "Intel Graphics" driver installed.
The HDMI driver may be packaged with the Intel Graphics driver.
Intel probably packaged it there, just as ATI does with it's video drivers.
So you probably won't find a download for an Intel HDMI audio driver on the
Intel site.

You can try uninstalling the Intel video driver and install this driver.......
