Thanks for your reply. This is my current bananian kernel
root@tv ~ # uname -a
Linux tv.lan 4.4.66-bananian #2 SMP Sat May 6 19:26:50 UTC 2017 armv7l GNU/Linux
Please let me know what other information might be helpful.
Afterwards I'll setup the server on current armbian to check whether stuttering still occurs. I have to admit that the last time I tried it was maybe half a year ago.
