:-P

Yup. I have been using rt for many years - and packaging it - for (very) 
low latency sound processing. Linux + rt + jackd + rtirq + threaded irqs 
+ jack clients, everything with the right priorities. Runs very nicely 
unless you hit an issue like the one I'm asking about[*]. Usually 
running snd_hdspm with RME hardware when in concert situations (this one 
with Asus mobo is my - quite old by now - desktop at work, but I'm also 
having the same problem in my Lenovo laptop).

[*] for example a whole concert for a 24.8 3D sound system with a remote 
ethernet driven D/A and running all the time with 64 frame x 2 buffers 
at 48KHz.
