In case it helps, Windows 10 just made their 'anniversary update' available in the last few days, and it's rolling out on some sort of 'newest computer first' schedule. You may have been updated (unless you have the Pro version where you can turn off these automatic updates). Then, by running another audio program, your system 'corrected' drivers somehow. Just a guess, but it helps to know all the possible variables.
