Recentemente enfrentei um problema com pulseaudio equalizer no meu PC com o Ubuntu 14.04, a única coisa é que cada reinicialização coloca pcm level em max db e o som fica distorcido.

### END: Equalized audio configuration
Eu tentei mudar a linha:
#load-module module-alsa-sink
para:
load-module module-alsa-sink control=PCM
(com início # e sem) ainda sem sorte, depois:
killall pulseaudio
pulseaudio -k
o som desaparece ou pcm volta para 100%
Tudo que eu quero é que o Equalizer seja ativado por padrão, cada inicialização com minhas configurações de som manuais serão mantidas. Há mais alguma coisa que eu possa fazer sobre isso?
