Is the mkv sync before conversion?
If yes, then share a debug output of Hybrids analysis. (read sticky)
If no, you can also try ffmpeg -i <path to input> -codec copy "<path to output.mkv>", but my guess is that this will also not work better than ffmpeg.
=> seems like you should fix your stream first by running it through tsdoctor or similar.
You could also try converting your file with some ffmpeg or handbrake gui, which process audio&video at the same time and try to handle 'broken' files. (depending on the tool you could convert to some lossless intermediate and feed that to Hybrid, assuming the intermediate is sync)
