How Can I Replace The Subtitles In An Mkv Container

So I extracted the audio and video from the original container and muxed them again along with the corrected subtitles and got a new .MKV file. But when I played it on my TV, I got an error saying that the audio codec is not supported. The original .MKV file played fine but when I remuxed the same files from the same container into another .MKV container my TV says that the audio codec is not supported.

I’m pretty much new to this stuff, so how can I solve this problem? Thanks in advance.. and sorry for my bad english.
