> Also, I sure that you can replicate the problem on a PC with only a single
soundcard, correct?

Correct! I found the bug with a single sound card, and then I reproduced with
one sound card, and then I reproduced with several different sound cards but
only one at a time, then I reproduced with several sound cards simultaneously.

> Have you ever taken a look at what your CPU usage is on this PC with all the
pipelines active with 'top -H'?

htop said me about mem:
Mem:1008M used:98M buffers:0M cache:102M

about cpu:
Avg:  6.6% sy:  1.3% ni:  0.0% hi:  0.0% si:  0.0% wa:  0.0% st:  0.0%

> You can also do a 'top -p <pid> -H' for a particular process
