hi all,

My android 55 inch TV is on version Android 7.0 Nougat OS.

Facing NO SOUND problem in all apps like Youtube, Netflix., radioonline.

If i restart TV then it start working and all apps have sound.

Then again i restart then sound stop working.

it is total random problem.

Reason according to me : Logitech webcam with inbuilt mic is plugged into USB. Randomly on start android assign that as default AUDIO OUT device.

Already Tried a) developers options, disable audio usb routing ENABLED...not solved b) soundabout crash on start c) Audio Router i had set speaker as default device and still not solved

My TV is not rooted.

Root Explorer helped me to read content of /etc/audio_policy.conf but not allowing to save it. if i try any change :

/etc/audio_policy.conf : https://pastebin.com/AcYhMUsP

Please help me in resolving this problem.
