The thread topic says it all, I'm on android 5.1 rooted encrypted and I hear this hissing/buzzing sound after every notification or any sound I played, I've searched the xda forum and I've found people having similar issue, they rma'd their nexus but most have the same problem still, does it have a fix? Or is it a problem of lollipop? As I've a Xpeia S on lollipop and I found similar issue on it, please tell me if you've similar issue, is it hardware related or software?
