My setup is MrMC (audio set to passthrough, change refresh rate on start / stop with a delay of 4 seconds, audio offset 0) -> Shield (audio offset 0) -> HDMI -> Denon AVR-S720W (7.1 surround, audio offset 0 and Auto Lipsync tried on and off).
I was noticing that the audio would be delayed or ahead depending on audio type: stereo, DD+, DTS and I'd constantly have to mess with audio offset options in MrMC, so I downloaded some AV sync test clips (https://sync-one2.harkwood.co.uk/suppor ... 080-files/) and installed an app designed for checking audio / video offsets on my iPhone (https://itunes.apple.com/us/app/catchin ... 41912?mt=8) and ran some tests:
It looks like MrMC will go out of audio sync +220ms to -120ms and some stops in between on if the audio track is 5.1 or stereo.
I don't seem to have this issue with the Netflix or Youtube app on Shield or with other HDMI devices connected to the Denon.

Re: Audio out of sync different amount depending on audio codec?
Hi,
Have you found out what the problem is and if there is any fix? I just recently switched from SPMC to MrMC on the Nvidia Shield and I am having a similar audio out of sync issue but apparently only on some video files.
Thank you.

Re: Audio out of sync different amount depending on audio codec?
I set an audio ahead offset of 34 ms on my receiver and that seems to have fixed the issue with Dolby Digital+ (5.1) content. However, stereo content and Atmos have different offsets that I have to mess with every time to get lips synced

Re: Audio out of sync different amount depending on audio codec?
I'm surpised that an offset of 34ms would change anything.
That's less than a frame in 24p, and "Normal" people can't notice a delay less than 100ms.
Furthermore, I don't experience those symptoms myself.
Could it be bad encodes?
Did you try with Kodi, VLC, ...?
Which version is it? Are you on Testflight?

Yes, the files play fine elsewhere.
In fact they even play in-sync on the Plex app on the Shield.
I am on MrMC 3.7-0 Git:2018-06-14-312a692.

Re: Audio out of sync different amount depending on audio codec?
just tried clearing data / cache on the MrMC app and starting from scratch. only change I made was to enable passthrough audio settings.
I then played a Dolby Digital+ 5.1 video and the audio was out of sync. tried disabling refresh rate switching: same issue. playing the exact same video on the Shield Plex app has no sync issues (with audio passthrough enabled and refresh rate switching on even).

I can share privately some sample video files that require different offsets if you'd like. Or I'd be happy to do some testing / provide debug logs as well.

Yep, samples that are positively wrong on your side would be great

Sent you a PM with 3 samples.
