Popup stating audio devices has changed

[MyriamBerger]

Hi team

I was on vaca for 2 wks, started up adobe audition versuin25.3.0.71 and now I'm getting a popup window about every two hours or so stating: 'The list of audio devices connected to the operating system has been changed. Do you want to open the Audio Hardware preferences? I did not have this message before my vaca. I click yes, and I have to re-choose Device class: ASIO / Device: Focusrite USB ASIO etc and then also correct my Audio Channel Mapping Device Channels.  What is causing this to happen and how do I fix this so that it doesn't happen again? I'm hardwired into my router and I have a new laptop. Thank you all!
