I realize that my previous mail was pretty verbose and has not much on-topic information
and I want to apologize for that babbling. I wrote that right after getting up in the
morning, while sipping my first coffee and being in a slight hurry before leaving to work.
My motivation was to give a confirmation on the principal working of the pisound o a RPi 3
Model B+ (for me). I'm using a FullHD HDMi display without issues.
I am seeing occasional graphical freezes of up to several seconds, but never as long as
you describe. Also that freezing display seems to be independent from the processing side
of things - it never harmed the ardour recordings, live sound of the effects in modep
(which runs in text mode), or DMX output when using it as a lighting desk via QLC+ on a
LxQt desktop (AFAIR).
Cheers,
Edgar
