I'm wanting to get the MHL 2.0 adapter for my phone, however the issue I currently have is my tv's speakers don't work because of the sound card in it. I use a surround sound receiver instead, but there are no hdmi outputs on it. It only has coaxial and optical. Is there some kind of adapter, hub, etc.. that exists where I can plug the MHL adapter into then have a hdmi and separate audio output from it? or am I going to have to get a new tv or surround sound receiver?
