That tends to be output when the system tries to start the sound player (duh) and finds it missing. It’s been happening to me on the Pi as I try to work out why the ALSA sound stuff wouldn’t build (because I hadn’t installed the libasound2-dev package, apparently, discovered eventually by poring over the config.log in desperation) and the vm defaults to some other sound player module. The fact that you are getting that message when you used not to, implies to me that you are somehow starting up the vm in a different way and the ‘proper’ sound setup is not being done.

Sorry it’s rather vague and waffly.
