Sound suddenly muffled

Hey guys,

 

I have a problem with the speakers on my iMac.

 

The audio was completely fine till yesterday (I'm not sure when exactly), out of nowhere, it started sounding very muffled. I don't know how else to describe it, it just sounds very, very bad (but it sounds ok through headphones).

 

I have checked the preferences and everything looks good, I restarted it but nothing really has seemed to work.

It seems to be a hardware problem, are the speakers blown? Or can it be some wire not connecting right?

 

(The iMac is a 27" Retina 5K late-2015 with macOS Sierra, if it helps at all)

 

Thanks in advance

 

Inês

You definitely need to uninstall MacKeeper and CleanMyMac3. Not sure if it caused your audio problem but they were both installed the day you started having the problem.
