USB Soundcard on Raspberry PI

The default sound card powering the 1/8 audio jack on the Raspberry PI 3 is not so great.  The default sound card requires a high system utilization and plays back choppy or stuttered sound in many cases when the 1/8 audio jack is used.  Adding a USB audio adapter is a great solution when better audio is required.

To disable the buit-in sound driver and enable a USB sound card:

  • nano /etc/modprobe.d/alsa-base.conf
  • add the following:

#blacklist built-in broadcom sound
blacklist snd_bcm2835
#Set USB Sound Card so it can be index 0 (default)
options snd-usb-audio index=0

  • reboot

Here is a USB audio adapter that I have personal tested and proven to work well on the Raspberry PI 3.
