The Windows/Linux bug has been sorted out, so you will need to just uninstall and reinstall Chromemote with latest version on the Web Store to correct this issue. Looks like there is an issue with not pairing correctly with some Sony devices. I am doing what I can to get my hands on a Sony Google TV device for testing. Please keep the feedback coming in. I really appreciate everybody helping me test Chromemote. I will be adding the ability to manually add an IP very soon.
