ALSA equalizer not working

Troubleshooting

file is an empty redirect, echo is not required for this but doesn’t hurt either :wink:.

Okay, please try the following:

cat << _EOF_ > /etc/asound.conf
ctl.eq {
	type equal
	controls "/var/lib/dietpi/dietpi-config/.alsaequal.bin"
}
pcm.plugequal {
	type equal
	slave.pcm {
		type plug
		slave.pcm {
			type hw
			card 0
			device 0
		}
	}
	controls "/var/lib/dietpi/dietpi-config/.alsaequal.bin"
}
pcm.!default {
	type plug
	slave.pcm plugequal
	slave.channels 2
}
ctl.!default {
	type hw
	card 0
}
_EOF_
