no lol, i guess u can do that but u can also just put the vlc volume on half, or something that i found usefull is lower the waves from the general volume on ur pc, not the master volume i have found that worked best at least for me.
EDIT: and also u mentioned it works fine for u on vlc, u dont need the speakers to be outragesly high, as long as u can hear the lower end of the masked ocean surf ur good to go with the ultrasonics, i thought there was a problem with my speakers because i can actually here the ultrasonics and changed them but turns out they were fine but because im still young i can hear the sounds so as long as u dont have that staticky sound when u got the volume on maximum ur good to go.
