Movie Playback Randomly Stops on UGOOS AM6B (CoreELEC 21.2-Omega)

Good day everyone,

I’m a bit lost and likely missing some details, so feel free to ask if you need more information.

The issue:

While watching movies, playback randomly stops — about 3 times out of 4. This can happen anywhere from 15 to 40 minutes into the movie. When it stops, it kicks me back to the menu.
From there, I can resume the movie, and it picks up again after about 5 seconds.

This issue only happens with movies — TV shows play fine without interruption.

Setup details:

  • I used the Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+ guide to set up.
  • I’m running CoreELEC (official) 21.2-Omega on a UGOOS AM6B device.
  • Kernel: Linux ARM 64-bit version 4.9.269
  • Model: Amlogic S922X rev B
  • Hardware: UGOOS AM6B
  • Dual-boot is enabled.
  • Device is wired to a NAS (no Wi-Fi connected).

Final notes:

If this is the wrong place to post or if you need additional information (logs, settings, etc.), please let me know — I’d really appreciate the help.

To do the installation i followed this topic: :[Guide] S922X-J (Ugoos AM6b+) CoreELEC installation and FAQs

I also applied the settings in that same post.

Thanks in advance!
