I connected my Surface via HDMI to watch some movies on the home theater system, but I'm only hearing sound through the Surface speakers. How do I get audio to go through HDMI so that I can use my nice home theater sound system?

Hi all.

I found probably a solution. When I connected the HDMI I only heard the sound in the surface and at the sound devices box the HDMI option won't appear, so I get in into Device Manager and Right click on my Surface and Scan for HW changes, then the sound starts to listen on the Home Theater. I expect this probably works in most of cases like me.

Regards.

Use the Sound applet in control panel to check what audio devices are installed. If you have a choice make sure the right one is selected.

With 11 pages on this thread and it is already answered few are going to see your question and have you read it through and looked at the possible solutions? If you have then it might be better to start your own question.

Detail what you have tried and what your hardware is, with laptops because everything is on the motherboard getting audio onto the HDMI is normally inbuilt but with desktops it could be different. Even with a desktop if you are using an integrated HDMI/sound card then that is the same as a laptop but if you have a discrete graphics/sound interface then that requires different settings.

    This is a driver issue.

    For me - I downloaded the drivers from:

    https://www.microsoft.com/en-us/download/details.aspx?id=49497

    There are a few drivers. I downloaded SurfaceBook_Win10_1701000_0.zip

    Unpack the zip file - Within there is a folder called:

    Drivers\Display\DisplayAudio

    Right click on IntcDAud.inf and click install

    Then disconnect and reconnect your hdmi.

    Worked for me.

    While this is an old issue that can happen repeatedly for various reasons, I will post the same helpful fix I use repeatedly as well with the original source with it. So the issue can arise due to various reasons (1 and 2 for me):

    1. Laptop/tablet/Surface Pro 4 went into screensaver modus while connected to an external monitor through an HDMI cable.

    2. Laptop/tablet/Surface Pro 4 went into standby/sleep/hibernate modus while connected to an external monitor through an HDMI cable.3. Laptop/tablet/Surface Pro 4 did not show the HDMI audio at all upon connecting the cable; mind you, this might actually be after 1 or 2 happened to you without you noticing it.

    Solution to reasons 1 and 2:

    solution by brun.ws:

    ,,Actually, I found going into Device Manager and disabling and then re-enabling the "Intel(R) Display Audio" driver solved the problem for me.

    1. Right click on the start button, and select "Device Manager", or press WIN+R and type "devmgmt.msc".
    2. Look for "Sound, video, and game controllers," and expand its section.
    3. Right click on "Intel(R) Display Audio," and select "Disable."
    4. Then right click it again, this time selecting "Enable."

    This was done on the anniversary update with the latest drivers. You may have to try unplugging and then plugging back in the HDMI cable between steps 3 and 4.''

    I hope this can help more people in the future as well and I hope Microsoft fixes this bug in a later update. They can even build in a temporary fix to just disable and enable this particular driver when bringing the Surface Pro out of sleep/hibernate/screensaver modus so we don't have to go through it manually.

    Good luck humans.
