Isnt the best thing to install the last stable 3.2.3 and then configire autostart.sh for the CIR and the blacks and we should be ok, or is it other features that isnt on the stable 3.2.3 that we need?

No colors are too dark this way, u need to set limited range in the video settings swell and this is only possible in Gotham Builds..
Multicore also jus works on the newer Nightlies..

The only problem for me is DTS-HR. I keep them as it is smaller to keep it as is than to convert them to FLAC. So I currently can't play those few tracks with gotham (should perhaps switch off passthrough for those).

As said i was getting Sound problems too out of nowhere, erasing my Userdata Folder completely and reflashing to 3.2.3 helped..
