buzzing sound when headphones connected

whenever I press on something I hear this mechanical buzz for 5 seconds then it stops until I press something else.

How do I fix this, should I return this phone?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

That is certainly not normal, however please try this as a possible fix: Main Menu > Settings > Apps > Smartconnect > Clear Data.

I'm shocked, your fix worked. How strange! 

Thank you so much

I get the audio buzz when I play a YouTube video - I no longer get the buzz from other apps - how do I fix it on the YouTube app?

[Aru-beddo]

The buzzing static is still there even when I mute the headphones. I press play on a YouTube video and I get static buzzing, which continues until I pause the video - and after 5 seconds it stops.

Its driving me mad :S

Sorry for so many posts, if I use the walkman app the static buzzing is constantly on until I restart my phone or after a long delay.

Even when the headphones are fully muted >.<

That is odd, however this is pointing to more of a software issue so I would advise trying a firmware repair:

Hello!

I have the same problem on my sony z3 compact. 

I bought the phone one month ago and I tried to do everything you suggest but with no improvements at all.

I have this problem only when I use an headset with a microphone (such as the one in the box). If I use normal headphones without a mic I don't hear any buzzing when I m touching my phone.

Could you please help me?

Thank you

Luca

I have nearly the same problem: whenever I plug headphones (with or without microphone) I hear buzzing, and it doesn't stop. I cleared smart connect data, even uninstalled updates, but nothing happens, the problem is: I don't have a windows PC...
