    Hi Marc,
    Please try only entering “-o plug:plugequal” in the command line.

    SOLVED!

    I was having the same problem as many: the equalizer just would not work with my HiFiBerry AMP+. After much web research and testing, I found the problem is in the alsa config file (/etc/asound.conf). Here’s how to fix the problem:

    To find out what sound cards you have on your system, display the contents of /proc/asound/cards:

    `$ cat /proc/asound/cards
    0 [ALSA ]: bcm2835 – bcm2835 ALSA
    bcm2835 ALSA
    1 [sndrpihifiberry]: snd_rpi_hifiber – snd_rpi_hifiberry_amp
    snd_rpi_hifiberry_amp`

    Here you can see my HifiBerry Amp+ is seen as card 1. However the ALSA configuration file (/etc/asound.conf) is pointing to card 0, the default card:

    $ cat /etc/asound.conf
    ctl.!default {
        type hw
        card 0
    }
    pcm.equal {
        type plug;
        slave.pcm plugequal;
    }
    ctl.equal {
       type equal;
       module "Eq10";
    }
    
    pcm.plugequal {
       type equal;
       module "Eq10";
       slave {
         pcm "plughw:0,0";
       }
       hint {show on;description "Equalizer for plughw:0,0"}
    

    To fix the problem, you need to change all references in /etc/asound.conf from card 0 to your card (1, in my case). Here is my corrected /etc/asound.conf:

    $ cat /etc/asound.conf
    ctl.!default {
        type hw
        card 1
    }
    pcm.equal {
        type plug;
        slave.pcm plugequal;
    }
    ctl.equal {
       type equal;
       module "Eq10";
    }
    
    pcm.plugequal {
       type equal;
       module "Eq10";
       slave {
         pcm "plughw:1,0";
       }
       hint {show on;description "Equalizer for plughw:1,0"}

    Now reboot your machine, then go into the Max2Play Audio Player->Advanced Configuration. Change the Sound Card to “plugequal – Equalizer for plughw:1,0”. I also changed my ALSA Parameters to “80:::” and the Command Line Options to “-r 44100-48000 -u hL::::”.

    Save everything, reboot again, and you should be good to go.

    Warning: I have a very basic system; just a stock RPi2 and a HiFiBerry AMP+. If your system has additional hardware or a different amp/DAC, your mileage may vary, but the basic approach should get you where you need to go.

    Hope this works as well for everyone!

    thanks for the reply, tried what you said but didn’t work if I select “plugequal” soundcard the player will start and music will play but there is no sound at all and if I select the “equal-equal” card the player wont start
