TL;DR:

To fix the MKV "no sound" error on Android caused by a lack of native codec support, you must bypass the default player by using a third-party app like VLC, convert the file to a supported format, or repair underlying file corruption via a desktop tool.
    ● Install an MKV-compatible media player such as VLC, Mobo Player, or Rock Player, or download a trusted codec pack like K-Lite to resolve unsupported audio issues like Chromecast's inability to play AC3 codecs.
    ● To repair corrupted MKV files using Wondershare Repairit, you must first transfer the video to a PC and use the Advanced Video Repair feature, which strictly requires uploading a valid, undamaged sample video recorded on the exact same Android device in the identical format.
    ● Exercise caution when downloading standalone audio codecs to avoid malware, and ensure that any successfully repaired MKV files are saved to a new storage directory rather than the original path where the damage occurred.
