I would like to reduce the bass and/or increase trebble. I have tried everything I can think of like: aumix -b---- aumix -b 100 aumix -b100,100P and so forth. Also tried these with the save option. Nothing seems to work. aumix -b q gives me 234, 255 no matter what I do. My hearing is about shot in high frequencies, so I want to see if more trebble may help me understand speech better. Using redhat 7.1. If you can make your bass actually change, please tell me how.
