could you please post the content of cat /boot/config.txt ?
it looks like the dt-overlay of your DAC is not loaded properly
Darfur here is my output when I get sound from the IQAudioAmp+ HAT card.
volumio@ampit3:~$ cat /boot/config.txt
initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
include userconfig.txt
Volumio i2s setting below: do not alter
dtoverlay=iqaudio-dacplus,unmute_amp
Volumio i2s setting below: do not alter
dtoverlay=iqaudio-dacplus,unmute_amp
Volumio i2s setting below: do not alter
dtoverlay=iqaudio-dacplus,unmute_amp
As soon as you see “through equalizer plugin” in Playback Options>>Output Device no sound is produced.
This is log when Simple EQ plugin is enabled and shows in Output Device and NO sound is produced.

Remove the plugin.
Disable i2s Dac
Select headphone as output
Remove line such as:
Volumio i2s setting below: do not alter
dtoverlay=iqaudio-dacplus,unmute_amp
from /boot/config.txt and userconfig.txt
Reboot.
Enable i2s Dac and choose boss.
Test.
Install the plugin and enable it. Reboot.
Let me know
Hi Balbuze,
Followed all your steps but after reboot, No Sound.
Volumio finds and loads the IQAudioAmp+ HAT driver. The mixer becomes either undefined or hardware.
Here is the output from:
$ cat /boot/config.txt

Is this the problem and solution?
As you can see from prior posts something happened at Volumio v2.657.

BTW if I add the lines:
include userconfig.txt
Volumio i2s setting below: do not alter
dtoverlay=iqaudio-dacplus,unmute_amp
to /boot/config.txt I get sound.
Also if I install and make Active the Simple EQ plugin i get no sound.
~$ cat /boot/config.txt
initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on

And they look identical !?!
The same issue with the 2.861 after update from 2.599
How can i reupgrade to the 2.802?
should be 'hw:1.0
Any idea where is the config file ? (I have the same issue)
