Increase USB current output

[Tim Curtis]

Software uses MPD's volume algorithm and Hardware uses the device's USB or DAC chip volume controller and it's algorithm. it may use a different curve and may or may not apply dither.

I see this device has 2 ALSA volume controls PCM and PCM 1 with no obvious way to determine which one (or both) are used for volume control.

Whats the output from the command below?

Code:

amixer -c2
