USB DAC

1d5cc1bd-40a9-4f26-b11f-96720682647c.jpg

Instead of using PWM audio via the Rpi GPIO pins (in case of using the Zero board) another option is using a USB DAC, available here.

To save space the USB connector can be removed so it can be directly connected to the Zero board or via a USB hub.

You may need to change the default audio device in order to make the sound play via the USB DAC. Just edit/create a file called /etc/asound.conf and insert this:


   pcm.!default {
       type hw
       card <number of your card>
   }
   ctl.!default {
       type hw
       card <number of your card>
   }

You can check if it should work when you start alsamixer, it should show your usb audio device by default.
