No audio The Recruit

Hello,
Most of my BR burns will play in one audio track or another but with the Recruit, not a single one will play on my Oppo using mezzmo. I have about 45 movies ripped so far, this is the first I'm having this issue but maybe more will come. I have tried all 3 tracks and while they will play on my PC, none will play when streamed to my Oppo.

All version of The Recruit on Blu Ray contain English Audio in both PCM and AC-3, as well as several foreign languages in AC-3. None listed show exactly 3 audio streams.
PCM and AC-3 are the two most basic and compatible Audio codecs of them all and no player should have problems with them.
However PCM is kind of rare. I'm wondering if it's possible that since the file doesn't contain DTS-MA or TrueHD that Mezzmo isn't bothering to Transcode the file and that may be the route of your problems. Try turning Transcoding off, setting all the advanced device options to 'Always Deliver' and streaming a DTS-MA file to the Oppo to see if you have any problems. Or go into the Device settings 'performance' tab and set the maximum resolution to 1280x720 to force a transcode and see if the audio in the 'The Recruit' rip comes back.

Now I'm wondering if it's possible MakeMKV 1.8.10 messed up the audio time-codes in the file, maybe you could try re-ripping with an older version.

No, Audio timecodes are always correct. 1.8.9-1.8.10 was putting occasionally incorrect timecodes on B-frames in video stream (and the difference was almost always less than 1 millisecond). These timecodes (on B-frames) are ignored by pretty much every software besides MakeMKV, and that's why it was noticed so late.

So that bug can easily be ignored and there is no need to re-rip everything?

Yes, this is correct. In the worst case you can re-run MKV file through latest MakeMKV, and it will fix the timecodes. Again, neither mkvmerge nor mkvvalidator would even notice the problem.

Will there be any log messages in that case?
I just re-run a MKV file (created with MakeMKV 1.8.10) through MakeMKV 1.8.11 and I have several log messages about AV sync issues and invalid timecodes:

For video, this is expected behaviour - 1.8.10 put invalid timecodes on B-frames and 1.8.11 detected (and repaired) it.

This is much more troubling issue - you have an audio hole with a duration of 45 seconds in your file. This certainly qualifies for "no audio". So the audio time codes are indeed incorrect, but this is not due to the harmless "bad timecodes on b-frames" bug that was fixed in 1.8.11 .
