Also, if they're looking for a dual audio version, that's a specific requirement. Not all platforms might offer that. They might have dubbed versions in different languages. Let me think—maybe the user wants to switch between Hindi and another language seamlessly. Some streaming sites have options for multi-language audio in settings. But if they're not using an app, maybe they need to convert or extract the audio tracks. Wait, the file is in MKV format, which supports multiple audio streams. So, if they have the file, they can use media players like VLC to switch between audio tracks. But how do they get the file legally? That's tricky.
