Hi guys,


A problem I've just started noticing is that when I turn up the volume on my Acer Switch 10, when I get to about 95% it starts to sound like it's in a tin can, and then when it gets to 100% it sounds like a horn blaring.  I have turned off the microphone as I've read in other forums that that can cause issues but that hasn't alleviated the problem.  I'm hoping someone has some ideas.

Most likely you're just overdriving the little internal speakers, this results in high distortion which typically sounds like honking. And if they're pushed hard that way for some time they get worse and honk more easily.


Sound system levels are normally set so that there's reserve for quiet levels (e.g. someone records the sound in a clip too quiet) to be boosted up to be high enough to hear well. That means on a normally loud source, using 95-100% is just thrashing the speakers.


Edit: unless you mean the effect occurs regardless of whether any sound is being played or not, if it howls when there should otherwise be silence then that would indicate the microphone isn't actually being turned off.
