I have a couple bugs with 801k & 801l.
First is the libreElec config addon under "System", there is no information to select (completely blank). Normally you would be able to do backups and such. This started with "k" and continued to "l".
Second is only on "l". Certain .flv files either have no sound or doubled sound. I've played with all the sound settings and have been unable to resolve the issue. Disabling all passthrough, DTS etc have no affect. Tried on two different tvs and both boxes. Going back to "k" fixes the issue. I'll look at the files meta data over the weekend but they're typical youtube files using AAC and .h264
