HDMI Audio not working. Hello I have a A2109A with last build I think from Lenovo : A2109A_A411_03_13_121126_GE. It appears that hdmi audio is not working. I tested with 2 different micro-hdmi to hdmi cables on 2 differents TV. I read some posts here and it says to "shove" the cable in. I think I did but with no sucess. As I plug the micro-hdmi the sound from the tablet is off and screen is mirrored on TV. By the way I had no success in playing video on TV alone using VLC and xbmc. The settings are ok but no sound at all on TV. As soon as i unplug the cable the sound is active on the tablet. If you can give me some hints before I contact Lenovo for guarantee service. Thank you.
