Solving Audio-Only Playback
M3U8 playback with audio only and no video is usually caused by video decoding issues or browser compatibility problems.
Common Causes
This issue typically occurs because the video encoding (such as HEVC/H.265) is not supported by the current browser, or there's a graphics hardware acceleration problem. Some mobile devices may also fail to decode due to resource limitations.
Solutions
Try switching to a browser that supports more video encodings. You can also use local players like VLC, which typically support more video formats.
Hardware-Related Issues
Sometimes graphics driver issues can also cause this problem. Updating graphics drivers or disabling hardware acceleration may help.
