I am attempting to get the alsaequal plugin working on one of my Raspberry Pi's, specifically one that I have wiped and reloaded with Raspbian Jessie. I have configured equal as described here: http://www.gerrelt.nl/RaspberryPi/wordpress/equalizer/ as well as configuring mpd as described here: http://crunchbang.org/forums/viewtopic.php?pid=330833. Unfortunately when I used my chosen music player (Mediaplayer - from here: http://petemanchester.github.io/MediaPlayer/) I get no output (Note that Mediaplayer uses mpd). I therefore installed mpc to try to see what was going on. When I use mpc to send a "play" command to mpd, the mpd log shows this:

Code: Select all

Oct 18 21:08 : client: [1] opened from local
Oct 18 21:08 : alsa_output: Failed to open "My ALSA EQ" [alsa]: Failed to open ALSA device "plug:plugequal": Operation not permitted
Oct 18 21:08 : output: Failed to open audio output
Oct 18 21:08 : client: [1] closed

Can anyone help me fix this?

ref to /etc/asound.conf
but i think now ( newer systems ) must use
nano /home/pi/.asoundrc
to define your soundcard, but you should have noticed
when you test the sound card ( without / prior to install the equalizer )

The file ~/.asoundrc is for user specific settings, whereas /etc/asound.conf is for system-wide settings.

so it works for you? funny, /etc/asound.conf not works on my "old" system,
but YES, on JESSIE it works again.

It works on jessie on my system, in that settings in /etc/asound.conf are picked up by ALSA. However, I have yet to get the graphic equaliser plugin working. I have reverted this system to wheezy now, but it would be nice to get it working on jessie soon so I can keep up-to-date with all of the work that the foundation is doing to improve the GUI.

Looks like there is something else going on here - I've reloaded the Pi with wheezy and I'm getting the same error. It seems there was another step involved in getting this working that I have missed out - oops!
