My Logitech G430 Headset has just randomly started echoing in Skype. I don't have any other voice chat software, so I don't know if it's just Skype.
When I select Listen to this device
in the Sound window, I don't hear an echo, but when I call the Echo / Sound Test Service
in Skype, I do hear the echo. Currently it is plugged in via the USB connector that it came with (Microphone + Headphone into a USB), I plugged it in manually and it still didn't fix the echo.
What could cause this?
