Audio drops for TrueHD with 96Khz sampling rate

[Spacefred 0]

when playing a video on my nvidia shield with TrueHD 96Khz, I get audio drops every 10-15 seconds. My receiver correctly shows that it is getting the TruHD stream at 96Khz.

I have the same issue with Plex (VLC is working perfectly).

Is this a known issue? Is emby using exoplayer and it's where the issue lies?

 

Thanks

Is emby using exoplayer

Hi, on android yes we are.

I checked it out but my issue is limited to 96Khz - the issue mentioned there has to do with 48Hz and high bandwidth. for me every 96Khz title fails regardless of total bandwidth. Exoplayer had an issue with 96khz DTS-HD that was fixed a few months ago so I'm thinking it;'s in the same line. VLC works without issue.

Do you know which version of Exoplayer that was fixed in?

Plex android TV 8.12.0 fixed it - they mention updating ExoPlayer to r2.12.1 in the release notes of the Beta 4 days before another Beta lists the fix. I don't know if that's the one but hopefully it narrows it down.

We are well beyond that release of Exo so that isn't the solution.

This was the solution for DTS-HD - this thread is for TrueHD

It looks like at the bottom there was a commit on Sep 11 which I assume made it into version 2.15.1 then?

I did not - interesting - what's the exoplayer version used by the current emby Android TV?

Right now latest beta has 2.13.2.  If you open the server log and search for "Exoplayer" it will display the version on that line

I'm looking at the Exoplayer release notes though and I can't make out if the commit actually made it into the releases, or not

I just looked at this more closely.  That code change is in LAVFilters, not Exoplayer...

Ok, thanks.  That's why I didn't see it mentioned in the release notes

Are you still having an issue with this?
