Tried changing audio settings from Stereo to digital and vice versa with no luck, I’d be happy even with 2 channel audio! Other MKV’s Play just fine.

Anyone have any ideas?

Thanks!

Welcome to the forums.

Yes, this is well known – use an earlier version of mkvmerge and you’ll be all right (or use the new version but turn off header compression in the track specific options for audio).

Never used the program before, Do you have any kinda walkthrough or guide and what I need to change exactly?

Thanks for your help!

Hey thanks for the help, that program is pretty easy to use, I also had a .mkv that came with a .srt , which I could not get to work and ran it threw the program you suggested and it fixed that one also. Only takes a few minutes per file!

Thanks
