Damaged speaker on Lumia 630 after update to build 10136 ?

[MarkXsama]

I might be a hardware issue typical for this model of Lumia. However, I did not notice this with WP8.1
My L630’s loud speaker makes a buzz noise when playing tracks or notification sounds - especially annoying with Messenger.
Anyone sharing the same issue, even on different models? Can someone share his opinions on this?

Maybe I am at wrong here to accuse the build, but it could be the cause, since OS and apps affect the behavior of devices.

My 1520 played very distorted notification sounds a few times last night while I was messing around with it.
But then it was normal again.

My 1520 has done that a few times. The first couple of times I rebooted the phone and it resolved it. The last time I didn't and it went away on it's own.
