Hello all,
I'm looking for a simple way to adjust treble/bass system-wide on my Arch laptop. I'm currently using alsa, but I'm open to other solutions.
Any insight? Bonus points for KISS-compliant solutions ;-)

I'm also trying to do the same thing, well, primarily only with mpd but I assume it would be possible to use this with almost anything. I'll post my progress here instead of creating a new thread since our goals are similar (and I've hit a brick wall)
I installed pulseaudio, and set up my asound.rc as such
pcm.equalized {
type plug
slave.pcm "equalizer";
}
pcm.equalizer {
type ladspa
# The output from the EQ can either go direct to a hardware device
# (if you have a hardware mixer, e.g. SBLive/Audigy) or it can go
# to the software mixer shown here.
#slave.pcm "hwplug"
slave.pcm "emu10k1"
#slave.pcm "plug:dmix"
# Sometimes you may need to specify the path to the plugins,
# especially if you've just installed them. Once you've logged
# out/restarted this shouldn't be necessary, but if you get errors
# about being unable to find plugins, try uncommenting this.
path "/usr/lib/ladspa"
plugins [
{
label mbeq
id 1197
input {
#this setting is here by example, edit to your own taste
#bands: 50hz, 100hz, 156hz, 220hz, 311hz, 440hz, 622hz, 880hz,
# 1250hz, 1750hz, 25000hz, 50000hz, 10000hz, 20000hz
#range: -70 to 30
controls [ -1 -1 -1 30 30 30 30 30 30 30 30 30 -5 0 0 ]
}
}
]
}
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.emu10k1 {
type hw
card 0
}
ctl.emu10k1 {
type hw
card 0
}
pcm.hda-intel {
type hw
card 1
}
ctl.hda-intel {
type hw
card 1
}
and in /etc/pulse/default.pa I made sure to use
load-module module-alsa-sink device=equalized
mpd is set to output to the pulseaudio server using the mpd-pulse package, and in the paman GUI I can see it is working fine, the problem is no matter what I change my equalizer settings to (as you can see I just put a load at max as a test) and restart pulseaudio, the sound remains the same.
I guess it's a problem under pcm.equalizer but I can't be entirely sure.

Ok, since nobody seems to know how to do system-wide equalization with alsa in a simple way, maybe I will lower my expectations a bit.
Does anyone know a media player with good and reliable equalization? (NOT limited to mp3 like xmms). Bonus point for a player that does both audio and video

Audacious (audacious-plugins) has a LADSPA plug-in. You can use this to set your equalizer settings graphically, then copy the equalizer values into your .asoundrc.
As for a player that has one built-in, there is Banshee. It can play audio and video (except for video object-format video). Unfortunately, Banshee is a bit on the heavy side.
