I have monitors in different rooms. I switch the default audio depending what room I am in but with the beta 3 update no matter which output i set as default, the sound only came through my main TV. The audio would not switch to the other device even though it said default. I installed the non beta 7.1 and the sound is back to normal so there is some issue with beta 3. Is there a download link for beta 2? I had no issue with that one.
