DigiAmp+ stuck on mute

Help and Support Help

Hi guys,

I’ve got a Raspberry pi 5 hooked up to a DigiAmp+ and have just gone through the steps of installing Volumio.

However, the digiamp+ won’t unmute. Adjusting the volume doesn’t trigger it to unmute either.

Any thoughts?

Hi Joe!
Try the following settings:

On the web gui:

  • Playback options / Audio Output
    • I2S DAC: on
    • DAC Model: IQaudiO Pi-DigiAMP+
    • save, no restart
    • it sets the following in the /boot/config.txt
      • dtoverlay=iqaudio-dacplus,unmute_amp
      • which continuously unmutes the amplifier regardless of playback status

Edit /boot/config.txt

  • change the following line:
  • from: dtoverlay=iqaudio-dacplus,unmute_amp
  • to: dtoverlay=iqaudio-dacplus,auto_mute_amp
  • restart
  • the amp will be muted when it doesn’t play anything. (Saves energy)

To enable SSH:

If you change the DAC model, you will need to edit the /boot/config.txt file again.
