Describe the Bug

I have two profiles for two games, they are identical except for the executable that is launched. However, for one game the audio is correctly muted on the desktop and piped to the Moonlight client, while for the other it is not. The working game is Hogwards Legacy, while the audio for Cities Skylines plays on my desktop's speakers.

No response

Problem exists for Moonlight-qt client on both Linux and Windows

Relevant log output

(I compared log output for both applications, did not see any relevant differences)

A guess, but I think Cities Skylines must be pointing to a specific device.

@ReenigneArcher I looked through some discussions on Steam and you seem to be right. Cities Skylines apparently always takes the default audio device. Is there a known way to force a particular audio device for an application?
