I have the Sony MHL adapater and when I use it on the Xperia Tablet Z SGP312 I am getting no audio output but video is fine. I used to get audio but one day it stopped and I just didn't bother trying to figure it out and used my phone instead. I would like to figure out why the audio isn't working through the mhl cable. The mhl adapter is fine as it works perfect with my other Sony Xperia devices it is just the tablet. Doing a backup right now and will try a reset to see what that does but was wondering if anyone else had an issue like this or any ideas.
