The VideoLAN Forums

I have been trying to play 4K files on VLC, they play the sound but no video, windows media player plays the video but no sound, MPC and Power dvd play the videos with sound no problem, I have tried nightly VLc and there is no option for gpu accelerated on my settings. when will this problem be fixed, and my graphics card is a GTX 1060 Rog strixx edition.

Try with VLC 3.0.0 nightly build.

Set it to use DXVA3 aka D3D11:
Tools -> Preferences -> Video
Output = D3D11

Tools -> Preferences -> Input/Codecs
Hardware accelerated decoding = D3D11 Video Acceleration

Then save, exit and restart VLC.

Method 1. Set your VLC player unmute

When a media player fails to play sound, the first thing that comes into people’s mind is to check whether the player is set mute. If you’re too careless to mute your VLC player at the last playing, then definitely you’ll get no sound. What you need to do is set your VLC player to unmute state.

Step 1. Click the speaker icon bottom right of your computer.

Step 2. Click “Mixer.”

Step 3. Unmute your VLC player, and check whether the VLC plays sound or not.

Method 2. Adjust VLC audio settings

If the above solution doesn't work out, try adjusting VLC audio settings.

Step 1. Run VLC

Launch VLC player on PC, and click “Tools” “Preferences” to get to “Simple Preferences” interface.

Step 2. Adjust audio settings

On “Simple Preferences” interface, click “Audio” tab on the left side bar to navigate to “Audio Settings.” Make sure the “Enable audio” box is checked and then choose “Automatic” at “Output” dropdown list.

Method 3. Convert your video to another format

If there is no expected result from the above solutions, you can use a video converter to convert your video to another video format, for VLC player sometimes fails to play video files like MKV and MP4.
