Behind every media file is a codec program. The codec is responsible for compressing video data into various containers (.mp4, .3gp, .mp3, .mov, .avi, etc.…) and decompressing the same files whenever someone needs to play them. Media players require the content of these containers (which could be any format) to be read properly; If not read properly, your media player will throw an error such as "Unsupported Codec," "Audio Codec Not Supported," etc. Media players cannot support all codecs. If a media player doesn't 'understand' a file, it will throw an error.
Please continue reading to discover the various causes of these errors and the different ways to fix audio codec not supported or missing error.
Here are some of the well-known causes of unavailable or unsupported codecs for audio files.
The result of a video file is data that has been compressed by certain codecs. When you attempt opening a video file with a media player, one of the first things done by the player is to check if it 'understands' the video data created by the particular codec; If it doesn't, it throws an error.
Media players have many codecs built into them. Each time you open a file, it simply finds the appropriate codec file to decompress your video file before playing it. If no appropriate codecs are installed/found, your media player throws an error.
While some media players will try to ignore/fix minor errors on videos, some don't –especially if the file is severely corrupt. File corruption can be caused directly by you or an infection on your device.
When, for example, your video plays with no audio or vice versa, you can be sure you're facing codec issues. Good thing, you don't have to manually do anything on Windows Media Player to fix this as it can be automated. You can fix this error using Windows Media Player. Just follow the steps outlined below:
Step 1. Launch Windows Media Player.
Step 2. Click the Tools menu and navigate to Options.
Step 3. Click on the Player tab to display options.
Step 4. Click on the "Download codecs automatically" checkbox and confirm your action by clicking "OK."
Step 5. Play your file again. You may be prompted to install the codec –click OK to confirm and install.
Note: Ensure that you have an active internet connection before clicking OK.
VLC is a versatile media player. It comes with many built-in tools for handling media files. VLC makes actions like converting media files from one format to another very easily. While VLC, at most times, fixes minor media file errors automatically before playing it, you can also fix errors such as unavailable or unsupported audio codec files manually using the software. Please follow the steps below.
Step 1. Launch VLC Media Player.
Step 2. Click on "Media" from the top menu, then find and click on "Convert."
Step 3. Add your video files to the file selection panel.
Step 4. Click the "Convert" button at the bottom of the page or hit ALT+C on your device's keyboard to convert your video.

Step 6. Choose "Video – + AAC (MP4)" or "Video – VP8 + Vorbis (Webm)" or any of the options available to you.
Step 7. Click on the Start button.
Once the conversion process is finished, retry playing your video file.
