Fix Windows 10 HDMI Sound Not Working – 10 Different Solutions

You can connect your PC, laptop, phone to HDMI TV using Windows 10. With the release of Windows 10  in July 2015, many users tried to connect their computers to HDMI external devices. But just like Windows 8.1 and 7, some people faced issue with no audio through HDMI.

You can experience 1080p “full HD” video and audio in a single digital interface using the HDMI standard. You need sophisticated HDMI cables and supported devices to implement this technology.  Then you can enjoy different sources like Blu-ray players, HD set-top boxes and advanced DVD players on HDMI TV or Monitors.

Some users are facing audio problems when they connect their laptop to HDMI devices. With the current Anniversary Update of Windows 10, you might have your problems resolved. Also, people will be using different sound cards like RealTek, NVIDIA etc. They face problem like realtek digital output has no sound in Windows 10. Some of them are using different brand laptops like Acer, HP etc.

Windows 10 HDMI problems are most common type of issues after its release. I noticed from user comments that, people are able to see video, but no sound through HDMI.  For this, you first need to update to latest Graphics drivers from the computer manufacture website. If this does not work out, you can try the default drivers by Microsoft. Most of them are looking for HDMI drivers, which could fix their trouble.

Typical Solution

For example, a user with Acer laptop(Aspire 7745G) who has upgraded from Windows 7 to 10, is trying to connect to a external Acer monitor (G276HL). He first tried using the HDMI connection, to get a signal via the HDMI port. But he failed. Then he resorted to the VGA method. This worked. But this is not a complete fix.

Then he uninstalled all related HDMI drivers and installed the original driver from Acer using the “Compatibility Mode”. This worked for him.


Another user with Dell Inspiron 15 N5110 had a similar problem after Win 10 upgrade.

He used the default MS drivers and also used the DELL website to find the latest audio drivers. But that was of no use.

So finally, he downloaded the following driver –  Audio_IDT_W7 driver. This can be done using the vendor website with the system tag.

But even though this driver is older than MS and latest drivers, the audio works fine. You can see the screenshot as below.

The second solution is to verify whether the audio on the playback device is activated in your Windows 10 “Sound” properties. For this you need to go to “Control Panel” by following many of the different alternative methods. Under Hardware and Sound > Manage audio devices > Sound, you need select the “Playback’ tab. Then you need to left-click the “Digital Output Device (HDMI)” feature. This makes the device as the default option for audio in Windows 10. Now try to reboot the device.

Some HDMI devices comes with different ports like HDMI1, HDMI2, HDMI3 etc. So after connecting your computer to your HDMI TV, make a note of the port you connected. Then using your TV remote, properly select the right port. Then try the second fix, by enabling the HDMI audio playback in Windows 10 sound properties. After this try to restart your Windows 10 PC. This can be a solution to modern devices with many ports.

HP users also faced problem with Windows 10 audio not working. For example, a user with HP ENVY TouchSmart 15-j053cl Notebook PC running on Win 10 Technical Preview connected to HDMI TV. The HDMI audio output is not shown in sound playback devices, but video is playing. There was an error message in the device manager.

"This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful."

One user in April 2015, solved this problem by downloading the Intel driver update utility and installing the latest drivers. They seem to have native support for Win 10.


#6 Fix It

If you are using a Microsoft Surface Pro Tablet having Windows 10 connected to HDMI TV, the mouse pointer may become erratic. Though this has nothing to do with audio problems, but this could have impact on sound properties also. There are scaling problems on the second display and screen rendering problems. So better wait for the final version before testing the TP version with Surface Pro and HDMI devices.

Another user starting using Intel Stick PC that came with 8.1. He then had sound problems with his HDMI device. It worked on the previous OS, but is not working with 10, after restoring all the drivers from 8.1. For this, you can try installing drivers in 8.1 compatibility mode.


#10 Fix It

The HP Omni 10 tablet can have some audio problems if connected to a HDMI device in Win 10. In this device, the HDMI audio is controlled by the “Intel Graphics Driver” also called the “Bay Trail” driver. So if you install the latest Graphics driver like version, you can have your audio problems fixed. It is found that audio driver has nothing to do with sound over HDMI, it’s taken care of by the video driver. If your audio is too low, you can have the Realtek I2S Audio driver (version 6.2.9600.4075) installed.

So sometimes updating the latest graphics, video drivers can also clear your audio problems.
