The Bass Cutoff value does not seem to be saved in the config file. Â Treble Cutoff appears to work. Â I tried to manually enter "Bass Cutoff". Upon reboot and increasing the Bass Gain, then rebooting to check the settings, "Bass Cutoff" had disappeared.
I was setting the Bass Cutoff to "1".
Edit: Nevermind (I think) Â -- user error.
Edit2: Not user error, upon checking again "bass cutoff: 1" did disappear.
