Thanks for the reply. It would seem that way, given that the buffer actually does absorb ~20 seconds of audio before blocking. It seems to be post-EQ, but I need to double-check that. > If the problem is indeed like flash, currently one thing you can do is > see if changing toggling tsched helps but that's just a work around at > best.

And yeah, I currectly route those apps straight to the card sink manually. Less than ideal. (My workaround for my desktop is a couple of vintage hardware equalizers.

I will remember to look into libao though.

I might (if I'm feeling adventurous) take a dive into the code this summer. I also don't have much free time now, either. Thanks for the pointers. --Sean
