Hello,after many and many tries and reading the internal tv manual i came to the conclusion that the TV hardware was ok to reproduce audio from external source (pc in my case),so i started thinking if it could be the software.

After a small search i was pleased to see that i could update it,so i spent some more time finding a compatible USB drive and downloading the new software,i installed it and i was VERY happy reading the last release note:

Q5431_0. 26.78.0
• No sound from external devices through HDMI connection.

So i installed it,tested again and what?it still doesnt work....im sure 100% the HDMI cable and the pc itself are fine,since i tried with some other monitor and it works.

Any idea on what it could help me?
