Hello.
I tried to get this to work from
http://www.thedigitalmachine.net/alsaequal.html and this forum thread. However, its EQ doesn't seem to work for me on my over year old Debian stable box with
http://www.thedigitalmachine.net/tools/ ... .6.tar.bz2. I had no problems compiling it though:
# nano /root/.asoundrc
# alsa force-reload

$ alsamixer -D equal

If I run it as root, then no problems. However, none of the music sound different with the EQ changes. I basically wanted to add more bass by increasing the left volumes higher.

I even tried rebooting in case something was stuck. What's wrong? I probably messed up somewhere!
Thank you in advance.
