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

Eli tuossa unbindasin webkameran. Samaan tyyliin katkoin piuhat bluetoothilta.
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.
