There is so much hearsay and mumbo jumbo about linux audio floating

the fact that we all seem to run from up to date to years old software,
makes any statement very much a your milage may vary...

Another tip, if you have to use a slot that
shares IRQs, then you
have to raise the priority of all the soft interrupt threads that
share the IRQ with the soundcard, otherwise you will get a lot of
xruns.
Afaik this is not necessary. The other softirqs get the default
priority of 50 so they already get raised.
