High frequency buzzing noises on Htc One S

[Haschee]

Hey,
I used to listen music with spotify on my HTC. But recently I have problems playing songs because there is a really annoying high frequency buzzing noise. It doesn't matter which song it is. I already reinstalled spotify and also changed the streaming quality. But the problem is still there.

It has to be a spotify problem because random music from my phone or YouTube sounds normal without any issues.

Can you guys help me?
