Hi. i want to introduce a simple program.
this script toggles values ​​"Left LOM Inverted From", "Right LOM Inverted From" in alsamixer -c 1 and increases the bass and treble.

power consumption:
when DAC enabled: 30-40 mA
when DAC disabled: about 30-40 mA
cpu load:
about 5% when DAC enabled.
about 5% when DAC disbled.

new version https://dl.dropboxusercontent.com/u/34051204/beats_0.0.2_armel.deb
