    HDMI output disappeared on laptop - TV no longer plays audio when connected with HDMI cable.


    I connected my laptop to the TV last night via HDMI to watch some shows when I noticed it wasn't playing audio like it usually does. Visual was fine, but audio was only coming from my laptop. Went through various settings and tried everything from games to mp3s, but it's like my laptop would not recognize my TV for the purposes of audio.

    When I go into sound devices, whether the HDMI cable is plugged in or not, there is no Realtek HDMI Output in the devices section, even with disabled/unplugged devices ticked. It just has "speaker/headphones."

    Things I have done:


    • Uninstalled/reinstalled speakers


    • Uninstalled/reinstalled/updated audio drivers


    • Updated Nvidia graphics card drivers


    • General Windows update


    • Restarting laptop

    It's not an issue with the TV as it plays audio fine when the Roku is plugged in. It's not an issue with the cable itself, as I have another brand new HDMI cable that I plugged in and I still get the same issue. It's worked normally from February up until yesterday when it suddenly didn't.

    Laptop is an HP 15-au018wm, Windows 10, all drivers are up to speed.

  2. No audio output though HDMI cable when connected to TV

    Hi Charles,

    I apologize for not addressing you in a timely manner. Let me help you in resolving the issue.

    HDMI cables do support audio signals, but not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer's sound card directly to the

    TV. Otherwise, you'll need to connect the audio signal to a different output device, such as external computer speakers or your home stereo system. Follow these methods and check if it helps:

    By default Windows does not route sound over the HDMI output. To change this we need to change the settings in control panel.

    Note: This will turn off sound from the speakers or normal audio output on the laptop. To get that back you will have to reverse this process.

    a) Press Windows key + X

    b) Click on "Control Panel"

    c) With the Control Panel in "Control Panel Home" view please click on "Hardware and Sound"

    d) Where it says "Sound" in green letters there are three options below that are in blue click on "Manage Audio Devices"

    e) This will bring up a window labeled "Sound"

    f) On the "Playback" tab there is listed the sound options available to you. One should read "Digital Output Device (HDMI)" Click on that.

    g) There should now be a check mark on that option, make HDMI sound output as default .

    h) The Sound should then play through your HDMI hookups to the TV.

    Write to us with the status of the issues experienced on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

    Thank you.

  3. Connecting a windows 10 laptop to a smart tv using a hdmi cable

    Hi,

    Thanks for posting your query on Microsoft Community.

    HDMI cables do support audio signals, but not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer's sound card directly to the TV. Otherwise, you'll need to
    connect the audio signal to a different output device, such as external computer speakers or your home stereo system. Follow these methods and check if it helps:

    Method 1
    I suggest you to refer to the suggestions provided by Karthik Vengaloor and Kaplana from the following link and check if it helps.
    Windows 8 audio through a hdmi cable doesn't work on desktop

    Please get back to us with updated status, we will be happy to assist you.

    if issue persists,



    Method 2

    Let’s first check if “HDMI Output” is selected as the default device.

    Follow these steps:



    1. Click Start and select Control Panel.

    2. On the right hand side of the screen, under View by:, click the drop-down icon and select Large icons.

    3. Click Sound.



    If you do not have the HDMI Output listed under “Playback” tab, right click in the playback window and select Show Disabled Device and Show Disconnected Device.



    If the HDMI Output option appears, right-click HDMI Output and select Default Device.



    Now the audio must be playing on HDMI.

    Play Audio through HDMI cable plugged into TV

    Thanks, but that's the opposite of what I asked. I have a desktop and am trying to play sound through the TV, using the HDMI port. Works for my 360, haven't seen the digital audio device option on my Windows 10 platform.
