Thats sadly not easily fixable without heavy Kodi patching and starting fixing the known very broken kernel codebase for AMLogic 3.14.
We have decided to not do that for K18 because the new kernel codebase is already at the corner and properly fixing the old one takes too much efforts that are basically wasted after K18 (the old way AML Kernel 3.14 is doing things is getting completely removed for K19). There is also a news article about it Development Update – LibreELEC .
Understood and appreciate the honest info. I'll just have to skip LE9 then on my WP2 as this is a deal breaker for my setup (Optical out to my receiver only), I can get by on 8.2.5 until the mainline kernel versions are hopefully stable.
