today i turned on my xbox 360 as i usually do, to find that it had been set back onto the lowest graphics setting, making my screen very pixelated, after fixing this problem i realised that there was no sound what so ever coming through the tv. I have tried playing a game to see if it was just on the dashboard that i had no sound but i have no sound what so ever. I can however speak and hear others through my xbox standard microphone.
I have tried using a different HDMI cable and it did not work, it was the same problem, my tv is not on mute, and i have re downloaded the most recent update but nothing seems to work. I have also come to the conclusion that its not my tv because i can still here sound when watching tv programmes whilst using the same HDMI slot and using the same HDMI cable.
The only thing which did get my audio going was the standard 3 prong cable which comes standard with the xbox 360 console. I was then able to hear everything as usual but the graphics suffered greatly, playing battlefield 3 i could hardly see anything!!
PLEASE HELP ME!! GETTING WITHDRAWAL SYMPTOMS ALREADY! ;)
