Beaglebone Black (BBB) with USB Sound Card (C-Media Electronics, Inc. CM106)

To play/stream music with the BBB and a USB sound card, the setup is very straightforward.

  • lsusb
Bus 001 Device 005: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device

  • sudo apt-get install mplayer
  • sudo nano /etc/modprobe.d/alsa-base.conf

change the line that is

  • options snd-usb-audio index=-2
  • options snd-usb-audio index=0

update uEnv.txt file to disable HDMI sound
  • optargs=capemgr.disable_partno=BB-BONELT-HDMI

 play some music
  •  mplayer http://8343.live.streamtheworld.com:80/KDFCFMAAC_SC


sound is pretty good. Better than the raspberry pi. No clicks and pops with BBB!
