Public bug reported:
By default, audio doesn't work on beagle platforms (Beagle C4, BeagleXM)
unless alsa mixer controls are manually adjusted. Even then, pulseaudio
consumes 70% cpuload as it can't map audio to the proper codec.
To enable audio, use alsamixer from a terminal and unmute 'HeadsetL
Mixer AudioL2', and 'HeadsetR Mixer AudioR2', then volume can be
controlled through 'DAC2 Analog' and 'Headset' volume controls. This
will only enable audio to work without Pulseaudio.
To get pulseaudio working, a configuration file needs to be created and
added to /usr/share/alsa/cards.
