Audio drop-outs on 4k BluRay rips

Hi,
I’m having issues with my Vero 4K+ when playing back 4k HDR movie files.
Video is perfect, but the sound drops out for a couple of seconds randomly.
My setup is Vero 4k to LG OLED B9 with sound output to a Sonos Beam via HDMI ARC.
I normally stream the movies from NFS shares on an Openmediavault server.
Same files play back perfectly from the TV’s built in Plex app, and from a Zidoo Z9s streamer also connected via HDMI.
Things Ive tried -

  • Changing HDMI cables (tried various Ultra High Speed 18Gbps HDMI 2.0 Cables) - same problem.
  • Copying source files to a USB3 connected drive directly attached to the Vero - same problem

The annoying thing is that sometimes the files play back perfectly for up to 20 minutes before the drop-outs start. Very frustrating.
Can anyone help? I’d hate to have to abandon using my Vero, as otherwise I’ve been very pleased with it and prefer the interface to the TV’s Plex app.

Ive uploaded a log here -

( I rebooted my NAS before trying to play the file - still getting audio drop outs )
Sorry - forgot to enable debugging - new log -

Is this similar to your issue?

Sound like it may be.
Ill check the audio bitrate next time.

Do these have TrueHD tracks? If so, it is unfortunately a known issue with Kodi. We are still working on it

Sam

Yes. Its mainly been TrueHD tracks.
However, when I switched to the DTS-MA track on one of the files, I still experienced a couple of audio drop outs.
Heres hoping for a Kodi fix…

If you put up a MediaInfo output of the file we can likely confirm it this is indeed the issue

Yes, seems to be an affected title unfortunately.

Thanks Sam.
In the meantime, I’ve remuxed the files using mkvtoolnix v48 which saves the core AC3 from the TrueHD Atmos as a separate track. Hopefully using this track will avoid the dropouts.

Yes, it indeed will.
