I checked alsamixer and it seems like it recognizes the device, but can't send sound to it. Also, my sound settings display no output, not even the dummy output. Can someone please help?

Your main soundcard is the 2nd one (the first is HDMI soundcard, attached to HDMI screen plug) .

So , in Alsamixer, press F6 , select 2nd soundcard : you will see more faders .Then set volumes and unmute faders (using arrow keys and "m" key to unmute. )

You can also install and run pavucontrol (Pulseaudio volume control) to access the 2nd sound card in the "output device" tab (click green button near it to make it default)
