    Hi MAX2Play community,

    I’m having problems installing the Rotary Encoder Plugin, ONLY when using Max2Play 2.47 with Pi 3B+ and the NEW IQAudio DiGiAMP+.

    When using my other Pi, which has an identical configuration – except that it connected to an IQAudio piDAC PRO – the Plugin installs perfectly and indicates it is running with process ID x.

    I have followed the relevant instructions:

    Easy control with Rotary Encoder and IR Remote


    http://www.iqaudio.com/downloads/IQaudIO.pdf

    And in particular looked through this existing forum thread:

    [SOLVED] Rotary encoder with IQaudIO Digi Amp

    But my problem is a little different – the software does not install correctly. Please can you help me?

    Thanks in advance,
    Matt

    Hi Bow,

    Which pins did you use? Should be the pin 22 for GPIO25 and e.g. pin 1 for 3V.

    Hi Heiner,

    As per the IQAudio_v30 instruction manual, I am using:

    GPIO23 (Pi Pin 16) – Encoder Pin 1 (right)
    Ground (Pi Pin 14) – Encoder Center Pin, 2 (center)
    GPIO24 (Pi Pin 18) – Encoder Pin 3 (left)

    GPIO22 (Pin 15) – Is being used for Mute, which does work but not latched.

    But the problem is the encoder SW is not running – TOP shows no additional process is spawned / no sign of IQ_rot.

    Thanks,
    Matt

    Hi Matt,

    That sounds like something might have gone wrong during the installation sequence.

    The script should be running regardless of whether an encoder is connected or not.

    Your output during installation should have been the following:

    Please try a new installation if possible and see if you can recreate this sequence.
    Both installation and reboot take a minute or two.

    Hi Heiner,

    Here are some further details – like I said, I have a standard install and the only variation to my configuration (compared to an existing working config where the encoder SW does run) is the inclusion of the NEW IQAudio DigiAmp+:

    Hi Bow,

    Thank you for the detailed report and sorry about the late reply.

    I was just able to recreate the issue. We are not sure what might have caused it since we did not alter the installer in any way.

    We will investigate further and let you know when we have the fix right away.

    Hi Bow,

    We were able to isolate the issue and add a fix to our current beta. To get it working, do the following:
    – Head to Settings/Reboot and make a Beta Update
    – Select „None“ in your IQaudIO menu, click save, reboot
    – Select DigiAmp+ again, reboot

    Now your Rotary Encoder should be working.

    Hi Heiner,

    Success!! Thank you very much indeed!! Rotary encoder volume control is now working with the NEW IQAudio DigiAmp+. Excellent!

    Just FYI, the mute button doesn’t work with GPIO22 (pin 15):

    When using the command line option:

    -o hw:CARD=IQaudIODAC -V Digital -Q -X 22

    The following output is seen:

    Update Configfile - existing Entry changed
Updated Squeezelite Settings - Restart Squeezelite to apply changes!
Trying to stop ... successfully stopped
Trying to launch ... NOT successful Click here to show detailed information
gpio: Unable to open GPIO direction interface for pin 22: No such file or directory
wiringPiISR: unable to open /sys/class/gpio/gpio22/value: No such file or directory

    I’ve not had time to debug it yet, and understand if you would prefer this to be raised in a new thread if required?

    Hi Bow,

    Thanks for the quick update!

    We would appreciate if you raised the different issue in a different topic so I can close this specific issue as solved 😉

    Hi, I am having the same issue, did this beta ever make it into the release? I am running 2.56
