    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

    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 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 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
