Problem with the sound when talking.

[Pineapple03]

Poor sound quality when talking through applications or Phone, the solution to the problem did not find. I did a global reset of the system, it did not help. On the Android 7.1.1 version, everything worked fine, but as soon as I upgraded to 8.0.0, this problem appeared.

Poor sound being played, ?

Or poor sound recording?

When I talk, all the sounds that are produced outside the conversation are of poor quality, and sometimes the volume of the sound jumps (slightly).
