Please try to contact manufacturer and ask about alsa configuration for this exact DAC. It should be enough to change the card number but looks like it does not work for some reason.

It looks like you want to use the Digital mixer control in your OAP configuration. It has volume and mute capability.
Have you shown us the content of the .asoundrc and/or /etc/asound.conf file? Analogue and Analogue Playback Boost should be set to 100% in alsamixer.

Your ~/.asoundrc file should probably be like this:
It's OK if you don't have a /etc/asound.conf file, it's another (optional, more global, higher-level) ALSA config file. The ~/.asoundrc file only applies to your (pi?) user account, whereas the /etc/asound.conf file could apply to multiple users on your system. Can you show us the contents of /boot/config.txt, current amixer output as well as a screenshot of alsamixer?
Have you read the guide at http://www.iqaudio.com/downloads/IQaudIO.pdf ?

As shown in the guide I linked, the unmute_amp option is only applicable to the Pi-DigiAMP+. You have the Pi-DAC+, right?
I'm pretty sure you should simply use: dtoverlay=iqaudio-dacplus

As I understood the guide dtoverlay=iqaudio-dacplus is for the Pi-DAC+ (the one I have) as well as Pi-DAC+, Pi-DACZero, Pi-DAC Pro and Pi-DigiAMP+ From the guide : a. For Pi-DAC+, Pi-DACZero, Pi-DAC Pro and Pi-DigiAMP+ use the iqaudio-dacplus b. For Pi-Codec+, use iqaudio-codec (05-01-2020, 02:29 PM)ktb Wrote:Yes sir I have removed the Unmute_Amp part of the line.
