I use Airport Express to stream music to my home stereo system. But every time I switch to Airport Express in sound preferences, the volume goes way down. It doesn't remember my last setting. This has been going on since I upgraded to El Capitan. In Yosemite it would automatically switch over to Airport Express and the volume was alway where it was the last time I used it. Is there a workaround for this?
MacBook Air, OS X El Capitan (10.11.6)
