Trying to cast to my Sony TV (about 6months old).
AllCast sees the TV, I can select it, but nothing shows up in GMusic unless I cast something else ia AllCast first, such as an image or audio file. At that point GMusic presents the cast icon, I select it and try to connect, but it just says connecting and never makes a successful connection.
I'm runing a rooted Nexus4 and have restarted after enabling the GMusic option in AllCasts settings. Hope this helps.
