Echo in my sound system

Sounds like someone might have been playing with your reverb (or other settings) in your sound driver application. Look in your Control Panel for something like IDT Sound COntrol or Realtek Sound Control. Should be a selection to return to default. If not, look around until you find the offending settings. Good luck!

Yeah if right click the sound icon at the bottom select recording devices, go through the devices by right clicking each one and checking the "Listen" tap. Make sure "listen" isn't ticked.

Hi, if this doesn't work, try muting the line in,

That worked for me
