Audio formats for sound devices kept reverting to 16-bit 48000Hz (DVD Quality)

Recently I have started using my 3.5mm Jack headset plugged into an HDMI to VGA adapter which splitted the HDMI signal seperately into audio (3.5mm) and video (VGA) output. Before, I was using it directly onto the laptop's audio plug, which is recognised as Headphones (Realtek(R) Audio) by default.

I always use the highest format possible, which is the 24-bit, 48000Hz (Studio quality) for all my sound devices. However, when using this adapter, which is recognised as Intel(R) Display audio, it seems to keep reverting the settings back into 16-bit. 48000Hz (DVD quality) which sounds really bad. Despite applying the changes in the settings, it will constantly change when rebooting or running multiple audio from different apps at the same time. This problem does not occur when using either the default laptop speakers or the previous output above.

    Have turned off all enhancements etc. but windows refuses to keep the setting to 24 Bit 192000 Hz Studio quality and changes back to 16 bit 48000 DVD quality and activates enhancements again!

    Have noticed that it also refuses to keep the sound on Dolby Atmos when you change the sound player, e.g. change the song on Youtube or switch to streaming, it loses the sound completely as it seems to lose HDMI sync, it also happens if you pause a movie/music.

    I have a denon AVC-A110 connected via HDMI and everytime I switched from passthrough to the AV amp playback it would default to DVD quality. I would have to go into sound settings and change it manually. I then had to run the troubleshooter which stated Studio Quality was not set to default. It would then change it to Studio Quality. But revert again next time.

    This was doing my head in. The "exclusive Mode" setting is something I had not checked before. I disabled it and it worked like a charm. Thank you so much.

    Disable Exclusive Mode: Windows has an "exclusive mode" feature that allows applications to take full control of the audio device. However, this can sometimes lead to conflict. To disable it:

    1. Find "Sound" in the Control panel.
    2. Locate your Intel(R) Display Audio device in the Sound Control panel, right-click it, and select Properties.
    3. Go to the "Advanced" TAB and uncheck "Allow applications to exclusive this device." Click "Apply" and then "OK".

    Hello LIAM KHOI,

    Welcome to Microsoft Community.

    I have read the thread you posted here in its entirety and I think it may be a compatibility issue between the adapter you are using and your laptop's audio driver. Because according to your description, if you connect the sound device directly to your laptop, the problem does not occur.

    Perhaps through some solutions can fix this problem, I have looked up some information for you, and sorted out the following solutions:

    Update Audio drivers: Make sure you have the latest drivers for Intel(R) Display Audio (audio output for adapters) and Realtek(R) Audio (audio output for laptops) installed. Sometimes, driver updates can address compatibility issues.

    Disable Exclusive Mode: Windows has an "exclusive mode" feature that allows applications to take full control of the audio device. However, this can sometimes lead to conflict. To disable it:

    1. Find "Sound" in the Control panel.
    2. Locate your Intel(R) Display Audio device in the Sound Control panel, right-click it, and select Properties.
    3. Go to the "Advanced" TAB and uncheck "Allow applications to exclusive this device." Click "Apply" and then "OK".

    Disable audio enhancement: Audio enhancement and effects may sometimes interfere with audio Settings. To disable them:

    1. Right-click the speaker icon in the system tray and select "Open Sound Settings".
    2. Under the Output section, click Device Properties for your Intel(R) Display Audio device.
    3. Go to the "Enhancements" TAB and check "Disable all Enhancements". Click "Apply" and then "OK".

    These solutions may be able to fix the problem you're experiencing, but if they don't work, you might need to find another way to replace the adapter you're currently using.

    Best regards,
