  • Change video format or codec that VLC can recognize. Except for VLC audio issue due to the codec incompatibility, VLC video playback is also bound to freezing, stuttering, etc as a result of the higher resolution/frame rate file that request more on computer power. The once-and-for-all solution to the issue without tweaking the complicated settings is to rely on a video converter such as WinX HD Video Converter Deluxe to convert video format, codec, resolution, frame rate, etc into a more compatible file that VLC can handle easily.

Free download the video converter and follow the steps below to convert file to VLC supported video and audio file.

Step 1: Download and run the tool. Click +Video button to import the media file. You can add multiple files at once.

Step 2: The tool will recognize as many as 370 formats and codecs, including 4K MP4, MKV, HEVC, H.264, VP9, WMV, AVI, etc, and is preloaded with 420+ device profiles, readymade for easier playback on PC, tablet, mobile phone, gaming system, etc. Once the output format window pops up, just choose a format VLC can recognize.

Convert MKV to MP4 for Playing in WMP

• Preferably, VLC supports playing MP4 with H.264 video codec and AAC audio codec.
• Optionally, you can do some basic edits such as trim off unwanted clips, crop the black bars, add external subtitles that VLC cannot do.

Step 3: Click RUN to begin converting video file to VLC friendly format. Then you can load the video and play it with audio on VLC.

Additional information: VLC has the knack for converting media files, but there are some people blaming for VLC no audio after video conversion. When tackling the issue, you must ensure the audio bitrate matches when you are converting, and make sure the audio codec is supported by VLC. A case in point, VLC cannot open the M4A audio encoder and doesn't work well with AC3 sometimes. Or else, try an alternative to converting video files.
