[SOLVED] IQaudio Pi-AMP+ mute always on

[Tim Curtis]

Thats a really old device.

The log shows that the AMP+ was detected and the commands sent to unmute it.

Here are the commands being used.

Code:

# Unmute IQaudIO Pi-AMP+, Pi-DigiAMP+
if [[ $1 = "unmute-pi-ampplus" || $1 = "unmute-pi-digiampplus" ]]; then
    echo "22" >/sys/class/gpio/export
    echo "out" >/sys/class/gpio/gpio22/direction
    echo "1" >/sys/class/gpio/gpio22/value
    exit
fi

Its possible that RaspiOS Bookworm has changed something in how /sys/class/gpio is structured.
Try running the echo commands from a terminal to see if there are any errors.

I also seem to remember that the AMP+ will be muted if the headphone jack is in use.
