Thanks for the advice,
I get no response when I click on the "asio configuration" button, which confuses things as it makes me think there's a problem with the driver. As for windows sound, there is nothing other than the mic & speakers that come up as devices. I'm a bit of a novice and I can't locate the sound mapper. I dowloaded ASIO4ALL but haven't used it. I will uninstall now haha.
I suspected that having the line6 pod go edit running simultaneously may have been the issue however it has persisted even when that and all other apps are not running
