Stream what you hear seems like a really nice program to stream audio from my windows 10 laptop to my DLNA speakers.
Unfortunately, the Stereoboomm MR200 is not supported. My MR200 is seen by Windows as a multimedia device next to stream what you hear.
I am able to use send to (which is built in in Windows 10) to connect to the MR200. It’s only available for local files. I’m not able to send f.e. youtube audio to the MR200 using that.
