Sorry to hear you are having issues.
What version of Windows are you running ( full numbered version - use winver.exe to get that )
Version of Deskscapes ?
The Audio in the Deskscapes app allows you to hear sound as it plays back in the app.
But will adjust the audio level up or down when played on the desktop.
The DSHost controls the audio as it plays back on your desktop .
Both can play at the same time if app is playing back and the dream on the desktop
are playing at the same time .
But they are separate audio controls .
Here's one of my Dreams with Sound plays fine with sound on my PC
