HDMI audio not working after battery dying

I was using my Surface Pro 3 to watch a video on my TV through an HDMI cable. My battery died, and when I reconnected my computer locked me out with Bitlocker. I regained accessed but the Surface would no longer recognize an audio connection to the TV.

In 'Sound', the only options are 'Speakers' and 'Headphones'. No other devices were available when I selected "Show Disabled Devices"

I attempted to reinstall the drivers for "Real High Definition Audio' and 'High Definition Audio Controller' in 'Device Manager'. I attempted the same with the graphics driver.

For some reason, I have two 'High Definition Audio Definition Audio Controllers' in Device Manager:

The one that does not work gives the following message: 

I also tried restarting with the HDMI cable attached.

Any other options for trying to get the audio to output to the TV through the HDMI cable?

My last updates were today and two weeks ago before.

Thanks very much.

    Hello SimonLiem,

    Thanks for reaching Microsoft Community and posting your concern here.

    Please give this troubleshooting a try as this is one of the ways to update the audio drivers manually.

    1. Open Device Manager.
    2. Expand System Devices and Locate Intel Smart Sound Technology driver (SST).(You will see two SST drivers, so kindly choose the first one)
    3. Right-Click and select Update Driver from the pop-up menu.
    4. Choose Browse my computer for driver software and then Let me pick from a list of available drivers on my computerand select High Definition Audio. Click Next.
    5. Test Audio.

    If above troubleshooting won't work, we want you to try resetting the device. Perform a USB recovery image on the device. This option reimages the entire device, including the partition on the hard drive. It is the most complete form of reset. You must have at least 16GB/32GB of USB Flash drive and it must be formatted to FAT32 prior to downloading the Recovery Image. 

    Note: This removes all the files and apps on your device. You will need to back up your data and reinstall the desktop apps or run updates after the completion. 

    To download the Recovery Image:

    1. Visit the page at http://www.surface.com/support/warranty-service-and-recovery/downloadablerecoveryimage
    2. Sign in with your Microsoft Account (this is the email address we asked you for at the start of the call)
    3. From the list of Surface devices available, select the device that you need a recovery image for

    Please note that while you will only be presented with devices that are currently registered on your account, you will also be presented with the option to get an image for a different type of device. If you try to use this option, you will be prompted to enter the serial number for that device 4. Download the recovery image using the button on the page 5. When the download bar pops up at the bottom of your screen, save the file in a location you will be able to find it.

      Format USB Drive:

    1. Insert your USB drive into the USB port of your PC.
    2. From the desktop, open File Explorer
    3. Tap and hold or right-click on the USB drive and choose Format
    4. Select FAT32 as the file system and enter a Volume label to name the USB drive, such as RECOVERY, and then tap or click Start
    5. Tap or click OK to erase the contents of the USB drive
    6. Tap or click OK when the format is complete

     Create a recovery drive:

    1. On your Surface or PC, open recovery image that you downloaded by double-clicking it
    2. At the top of the window tap on Extract and then Extract all. Select the USB drive you formatted earlier for the location and click Extract.

    Perform USB Recovery:

    1. Turn the Surface off by pressing the power button
    2. Insert the USB recovery drive into the USB port
    3. Press and hold the volume-down (-) rocker
    4. Press and release the power button
    5. When the Surface logo appears, release the volume-down (-) rocker.
    6. When prompted, choose your language options and keyboard layout
    7. Select Troubleshoot
    8. Select System Image Recovery. Recovering this PC. If prompted for BitLocker Key, tap Skip this Drive.
    9. Select Repartition the Drives

    Hope this helps.

    Kind regards,

    StevenK
