I just pushed the following fix to git:
* A simple equal.conf is installed at /usr/share/alsa-lib/alsa.conf.d:
ctl.equal {
type equal;
}
pcm.equal {
type equal;
}
* The example is updated to:
pcm.equalizer {
type equal;
# Modify the line below if you don't want to use sound card 0
slave.pcm "plughw:0,0";
# or if you want to use with multiple applications output to dmix
# slave.pcm "plug:dmix"
}
# Use the equalizer as default PCM
# pcm.!default "plug:equalizer"
# Usage:
# $ alsamixer -D equal
# $ aplay -Dplug:equalizer foo.wav
(which is also simpler)
This makes "alsamixer -D equal" work, even if alsaequal is not configured in
the user's asoundrc/system-wide alsa.conf.
This should probably be documented in README.Debian, since it diverges from
what upstream suggests (altough upstream's way would work anyway).
Cheers
