[Voyage-linux] noise when using new mubox firmware in cubieboard 2

[Joseph Chu]

Hello Punky,

the file is flac format (16bit/ 44.1kHz), which is from a NAS.

i already disabled the onboard sound i.e. output 1.
i also have rsize=8192,wsize=4096 in mount option.

actully i after i listen more carefully, the problem should be sometime L
or R channel has a very short drop of sound.

i first checked my DAC to amplifier connection but they are good.

i also checked the system load but they are not heavy, less then 5%

by the way, i didn't power off the cubieboard (always on) while i power off
my DAC and Amp after i listen the music.

Joseph
