I was not suggesting you leave it off.Hi: Thank you so much for your interest! Very much appreciated. Yes. I have turned on streaming using both methods in the material that you sent. Presumably that is why I can cast MP3, WMA lossless and WAVE files. I only have issues with ALAC (my predominant files) and FLAC (my other files). I may try turning off the firewall, but that would not be an ideal solution. I wonder if this could be a Google Mesh issue.
Are all files in your Music library in Windows?
