changes don't seem to have any impact

I'm trying to eliminate all bass from the audio on a Fedora38 system (due to some really crap quality earbuds that blow out the low end to the point where I can't hear anything). I was hoping that this app would get the job done, but none of the changes that I've made seem to do anything at all.

I dragged the low end frequencies to -26 in the "Graphic EQ" view, but there's no noticable difference. The "driver status" shows "processing" for "Processing state" so I think (but I'm not certain) that its doing something, but definitely nothing that my ears can detect.

All of this might be user error, but I'm not at all sure.

i'm attaching the current config that I'm using, in the hope that maybe it clarifies what I'm trying to do
