Audio Issues

Hello,

When playing Master Chief Collection on PC, I am getting an issue where when I ALT-TAB to my other monitor the icon on my Taskbar disappears but the audio continues in the background (I can hear music, gun sounds, etc.) as if the game is running, but with no display. I check Task Manager to see that it is not showing up with no way to force close. The only thing that helps is a quick restart of the system. I could be accidentally hitting my Windows key perhaps according to when I saw this in a different thread but nobody provided any additional insight or support. Hoping someone can maybe help explain what is happening or if I am not the only one having the same issue.

This started recently with the update to fix matchmaking from 6/25 or so
