    All working great, but i cant use equalizer with squeezelite.

    My squeezelite settings -> soundcard: plugequal
    Command line option : -o hw:CARD=IQaudIODAC -V Digital

    Any idea?
    Best regards,
    Marc

    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!

    HandyGuy …

    Thanks – perfect solution!

    I have 4 Raspi w/HiFiBerry cards of different types and your solution worked for them all.
    So simple … the solution is independent of sound card type. I wonder if it works for bluetooth speakers as well?????

    Again, thank you for taking the time to post and help others.

    No problem, Bob. Happy to help. I saw some others on this thread were still having problems, but no idea if they were able to solve them. Hopefully they were able to get it working.

    Your mention of the BT speakers is interesting. I’ve tried several variants of BT configuration with M2P but never got it to work properly. My goal (slightly different than yours) is to set up the RPi/HFB to act as a Bluetooth sink so I can stream from my phone/tablet into M2P and have it play through the connected speakers. That would allow me to listen to music other than what is on my home media server.

    The last time a poked at this was around a year ago and never got it to work right or consistently. But, the tech has changed in the past year so I may pick this up again with a new RPI3 and see if that makes any difference.

    I still have issues.
    Even altering the asound.conf to show „1“ ; the option in the drop down is still 0 🙁

    The HandyGuy /etc/asound.conf fix works perfectly, but it overwritten every time I restart the RasPi.

    How can I make the changes permanent?
