Thanks to Onyros for pointing out Alsaequal; my spontaneous desire to see an equalizer for the console seems to have been satisfied.
That’s running on Arch, just because there were already PKGBUILDs in AUR for it and its dependencies, and I wanted to get the chance to tinker with it before making the jump to Crux. If I get things working my way I’ll put Pkgfiles on here later.
Setting it up takes a quick configuration file that can (probably) be cut-and-pasted from the home page. Mine worked cleanly without any changes; depending on your card assignment, you might have to adjust a number or two.
Otherwise it seems to do what it claims to. The next step is to run it up against mocp and see if they play nice together. Pun intended.😛
