However, I also noticed that a few modules are not loaded again after restarting PA, namely /module-device-manager//, module-x11-publish, //module-x11-cork-request/, and /module-x11-xsmp/. I've also checked pavucontrol (thanks for mentioning it), and it looks like the equalized sink doesn't get any signal until I switch the output in the playback tab (but then it reverts back to the unequalized 5.1 sink after playing another audio or video file) or I restart PA from terminal. Also, as for the issue with Flash, interestingly, if I switch to the equalized sink inside pavucontrol, there is no stuttering apart from for a short time after I switch, but, again, this is a temporary solution.
