I'll investigate this... But I think it's an issue with ACDB. But I don't know why the sound would work otherwise..

The old Dolby implementation is incompatible with Oreo, I need to make a new port from some a Oreo release. Furthermore the LOS audioserver needs to patched with that: https://github.com/LineageOS/android_frameworks_av/commit/397691fc1009c7522d6b8b36e9e71c34daf6f6de For some reason, that one is included in 14.1, but not in 15.1 (yet). Maybe we should apply that one manually, like we do with the rotation-fix?

Seems the [PORT] [8.0+] Dolby Atmos™ for Oreo 20180220 [Standard/Unity] seems to be working. I used the unity version and it has only some glitches within the UI. The sound seems to be working.

This isn't the place to track this. Looks like "the boys" on xda figured out some sort of combination for integrating Dolby Atmos through Magisk. Whatever.
