I did the same things. Replaced sketch, upgraded to a micro, using the same hyperion.ng config as Daniel except for the led amount and unfortunately still have slow downs.
@danielfmo, please tell us a little bit more about your media storage. Maybe this has something to do with it.
I am running the emby for kodi plugin and have my media stored on an unRAID server that runs emby server and shares the media files through samba to my odroid-c2. All connected through gigabit ethernet. I am playing my media with the direct paths option. So no transcoding happening.
What is strange as well is that I was streaming the world cup games through the “orf” addon in kodi. It’s my countries TV station and they have a livestream feature. I had no slowdowns while streaming the world cup games.
Will next try watch something that is stored locally on the emmc storage of my odroid-c2.
I have w2812b LEDs connected, Daniel has 4wire LEDs connected, could this be a factor?
