So you suggest to raise the priority of associated
soft interrupt
threads higher than the default prio of 50?
Yes I do. Quite possibly the situation has changed since 2011, as the
rt patch is constantly evolving and being merged into vanilla.. I also
verified my results by asking the rt devs on IRC (not that this
constitutes proof), and a couple of them concurred that this would
indeed be good practice.

If this is addressed to me personally, I don't
base my statements on
hearsay and mumbo jumbo. I've addressed this specific topic on
LAC2011 in front of an audience with very knowledgeable people. If I
were postulating statements without having a foundation for it at
that talk the audience would've pointed me towards that.
I could have misunderstood your mail of course, it is not totally
clear to whom you address your reproaches. If so I apologize
beforehand.
I'm sorry if it came across as a personal reproach, it was in no way
intended as such! It was more of a general statement about linux
audio and the associated lore floating around on the nets, much of it
outdated or even untrue nowdays. What I wanted to make clear is that I
was not simply repeating some advice found on the internet somewhere,
but rather based my comment on personal experience.
