This add on works for equalizing but causes audio bugs. some websites have stopped working, e.g. videos on nyt homepage have no sound.

on youtube it causes volume increases every time you seek to somewhere in the video or skip.

changes video players sound if jumping on timekine

only extension for sound quality

It's either stuttering, or ramping up to maximum loudness. In every case, it doesn't work reliably for more than a few minutes. It works, but you'll hate it.

This EQ add-on turns itself on during video playback, even though it is turned off.
Also, there may be a problem with the gain, or the sound is cracked compared to other EQ add-ons.

Does this sometimes decrease the sound of other applications automatically (not always)? And boost the current playing to an annoying level. Very wierd. (BTW, I also installed "600% Sound Volume" but disabled in that tab, because of its shortcut support. I don't want to uninstall that.)

The EQ works but the audio just gets louder and louder over time...
