Fix stereo audio sound orientation (credit phhusson)

As the left & right channel stuck in Portrait position, in landscape mode the left & right speaker play the left & right channel (creating somewhat mono sound)

On Samsung firmware, the sound orientation will change automatically, which isn't on GSIs. To partial fix this:

• Get into ADB Shell (or Termux but not tested) and type am start-service me.phh.treble.app/.REPL then wait for 10 seconds
• After that, type/paste this:

echo '"g_hw_display_rotation=1 :android.media.AudioSystem .setParameters' | timeout 1 busybox_phh nc localhost 8800

• Set the g_hw_display_rotation value with your daily tablet orientation use (optional):

• 0 = Portrait (default)
• 1 = Landscape (prompt above)
• 2 = Reverse portrait
• 3 = Reverse landscape

• Profit!

You must do this every time you do reboot. Proper fix will be implemented soon on TrebleApp by the respected developer (as i can't code)
