I’ve just installed 11.3 on my laptop (Nexoc E619).
My soundcard was set-up too, as an Intel 82801H (ICH8 Family) (YAST Information)
It is listed however, under System-Settings>Multimedia as HDA Intel (ALC268 Analog) which I believe to be correct, after having looked at some older threads.
I can actually play music etc. but with the small problem, that the repeat ‘skips’ some ms at, what it looks like to me, random points.
Even playing the testing sound in YaST gives me a different skip-pattern each time.
