[...] Looking at the graph, it appears that your DSP load is hovering

running it with the threshold set to 90%. (I don't recall exactly
how, but I think there's a /proc/sys/kernel control somewhere.)
It would be nice to know which one really is :) Here are what I have here:

My eyes can't find anything related, but you know how intuitive these
things are ;)
