15.b6 audio missing in one machine, working in another

15.b6 audio missing in one machine, working in another pretty much says it all..

same project, same media, same location on both machines
- one machine is at home, after upgradeing to 15.b6 the existing audio does not exist according to Resolve, even playing the files in the media page
- one machine is in my studio downtown, and it can see and plays audio as expected
- both machines ran with audio on Friday with 15.b5 installed
- both machines are w10, all current updates, drivers, desktop video etc

on the machine with no audio i have tried to toggle audio output options in pref's, and matching restarts, with no joy

here's a phone shot of both machines, one local, one via VPN displayed on the same screen at the same time, note both running the same clip, in loop, locked playback at 24fps, one has no audio, the other one has no noize;

seemingly the installer changed my default mini monitor to system on one machine but not the other.... hope this helps anyone else who runs into this

It actually did help in my case, thank you for the advice
