it is the content of file produced by "alsactl store -f abc.txt"
alsactl is an alsa-util which store/restore the setting of the sound cards
when you logout/login or the system is shutdown/boot
BTW , it seem that the slider cannot individually control left or right
channels volume
How about selecting other CTL devices such as pulse (alsa-pulse plugin) or
equal ( alsa-equalizer plugin )
