Testailin avlinux 5.0.3.
Pyörittelin muutamaa kanavaa Ardourissa ja katselin, mitä top:a tapahtuu?
Muuten hyvä, mutta vilahti jotain mikä viittasi multimediakorttiin.

Jos vaikka tappaa hiiren erehdyksessä, niin sama rimpsu, mutta unbind tilalle bind.
Ei isoa vaikutusta, mutta ei topissa enää turhuuksia?
DSP-kuormat heiluivat 70-87% välillä.
Nostin chrt:ä jack:ä ja Ardouria. Pudotin näytön prio:a sekä hiiren prio:a.
Nyt heilunta vain pari %.
Siten lisäsin monialue limittereitä kunnes kuormat 97-100% ei xruneja.
Poistin kuitenkin turhat modulit lsmod->modprobe -r <nimi> used by ensin, copy pastasin samalla scriptiin.
Edit: Jos on pulseaudio kannattaa se tappaa.
