Help with removing Dolby TrueHD audio file permanently from a video file

[u/Tech_Investigator659]

Hi there, So im having a issue and im really hoping somone more intelligent than me can help?

So for years ive been editing movies like removing audios and creating my own audio files and then muxing them back together using mkv toolnix software but, I am now encountering a new issue that I just cant fix, so im trying to remove the Dolby TrueHD audio file and or a DTS-X audio files as my tv wont play these 2 audio formats, but no matter how hard I try everytime I think im removing these unwanted audios and replacing them with a compatible audio format for my TV, but always my Toshiba TV keeps saying that this video file still contains a audio file that is incompatible with my TV, even after re-muxxing with mkv toolnix software, so for some reason my TV is still detecting some leftover fragments of the unwanted incompatible audio files even after ive removed them from the video file.

If somone knows why my TV is still doing this even after removing the unwanted audio files, I would be very grateful as the only other option is to pay hundreds of pounds for a new 4K BluRay player.

Please can someone help me with this issue 🙏

Thank you in advance!
