    we have sucessfully installed Max2play, shairport, Squeezelite and alsaequal using the Instalation file provieded:

    But when configuring the Alsaequalizer with Squeezelite using “-o equal” option it fails with the below error:
    $] /opt/squeezelite/squeezelite -n max2play -o equal

    *** glibc detected *** /opt/squeezelite/squeezelite: double free or corruption (!prev): 0x00049528 ***
    Aborted (core dumped)

    Please find the asound.conf file:
    $] vim /etc/asound.conf
    ctl.equal {
    type equal;

    pcm.plugequal {
    type equal;
    slave.pcm “plughw:0,0”;

    type plug;
    slave.pcm plugequal;

    Able to start and use squeezelite with “default” options sucessfully but failed while we are trying to start the squeezelite using the “-o equal” to work with alsa equalizer.

    Here is our board aplay -L:
    [email protected]:~$ aplay -L
    Discard all samples (playback) or generate zero samples (capture)
    PulseAudio Sound Server
    Default Audio Device
    Default Audio Device
    Direct sample mixing device
    Direct sample snooping device
    Direct hardware device without any conversions
    Hardware device with all software conversions
    [email protected]:~$

    we are able to make the alsaequalizer work with the Mplayer using:
    $] mplayer -ao alsa -D equal <song name>

    and we are able to get the equalizer throught “alsamixer -D equal” command.

    Could you tell us where we went wrong …..

    please see the startup options of Squeezelite to get the correct alsa output for the equalizer with the correct asound.conf file (“-o plug:plugequal”). You may see the correct settings when using the webinterface to set up the equalizer with Squeezelite in the Debug Output at the end of the page.

    You may also have a look at our free SD-Card images that are preconfigured for use as audioplayer. Most platforms need different settings for sound and asound.conf (depending on Ubuntu / Debian and their version).

    Thanks for the reply.

    As suggested, we have downloaded the IQaudio image for raspberrypi board from the Max2play site and found no differance in the configurations files.

    Below are the differaces found with respect to the Rasberrypi image:

    OS: debian wheezy
    GLibc: 2.13

    Our boar:
    OS: Ubuntu 12.04
    GLibc: 2.15

    Alsaequal is working fine with the Pre-Compiled image of Raspberrypi but getting error when we do the same with our Ubuntu image:
    *** glibc detected *** /opt/squeezelite/squeezelite: double free or corruption (!prev): 0x00049528 ***

    we are getting issue when we are trying to connect the Alsaequal using Squeezelite, but works fine when we connect with Mplayer or Shairport.

    we have used “plug:plugequal” as suggested but dint helped much. could you please suggest some more options where we could missed out …..
