Good evening everyone.I have a strange problem and i need your advice.
I own a cheap wm8650 based epad,bought from china.At first worked ok,but suddenly shut down and i couldnt power it up.I use the reset hole,power it up and then my problems started.With every rom(even the latest one 1.3.0),when the pad is on main outlet,works ok.Everything is ok,till i unplug the power,and the pad runs on battery.Then the operating system treat battery as empty,and shut down the pad automatically.I have tried many roms,from many forums,nothing changed.After a bit of debugging,i found what causes it.If i change bootenv file the line setenv wmt.audio.i2s wm8900:ff:ff:ff:ff to setenv wmt.audio.i2s vt1603:f1:f2:ff:ff,i have no sound,but at least i can have my pad running on battery.By the way the module wm8900 is the proper module for sound,since when the pad running on main power and not on battery i can listen fine to music and all system sounds working.I dont know what else to do,and i am looking for some help,thanx a lot.
