So I sold my Nexus 7, for the 8.0, for the MHL capability because I have the AppRadio2 and want to output the video onto the screen and audio to the car speakers. The only problem is that it doesn't seem like the 8.0 outputs audio through the mhl cable. I've tried multiple cables multiple external displays... The works. But can't seem to get audio to an external device. I've also tried an audio output app and that didn't work either. Any information is helpful. Thanks in advance guys
