Windows 8 Music App Volume lowers down when in background

I had the very same problem, but, in my case, Steam was causing the problem. I turned Steam off, and *bam* (literally, the volume was 100...) the problem solved. I would recommend turning of some "suspicious" applications which might be using audio.

I've (now had) the exact same problem caused by the exact same application (Steam). As soon as I closed Steam, the volume stopped fading when the app is out of focus. Thanks for sharing the solution.

Yep Steam was the culprit for me too.

Moral of the story is as follows 1)Windows key + x 2)control panel 3)Hardware and sound 4)Sound 5)Communications 6)Do Nothing 7)Apply or OK

thanks that solved it for me. I can play music and have Steam open now
