    Have you recently installed any video-related apps that may have messed with codecs and/or defaults for videos?
    I didn't remove it so it's definitely a software issue of some sort. It's not there. I've used it a lot, and now it's gone.

    Most players, including Movies and TV won't play the audio for mkv files. I have 5k player which does so I use it as my default. Well recently the defaults are reset, Movies and TV is my default and the check box to change that is gone. I don't know what else to say lol. It's just gone.

    Use the little icon to the left of the video icon above your post. 'Insert Image'.

    Again, do you have any system restore points that may be relevant?
    - you will only have some if you enabled system restore in Win 10.
    (Do you need guidance on system restore points?)

    As to any other steps for fixing this, at present that's guesswork.

    Try creating a new user for test purposes, and see if you see the same problem when logged in as that user.

    You can try running SFC /SCANNOW from an admin (elevated) command prompt.
    [Windows key + X, click command prompt (admin)]
    This will check your system files.
