Hello
I have a problem in the voice of external speakers
I do not know what's happened

Speakers do not work ever
But sometimes I hear the sound when charging
But when I call someone I can hear his voice, and He can hear my voice
I did Flasher more than a thousand times, but unfortunately the same problem
Also when I type this command in xterm
root

I hope to find a solution to this problem
