Problems with sound on bbc channels



Regular Member
Hi folks,
Ive been having a lot of trouble with the fta sky channels, mainly the bbc ones. I get perfect signal, and all of them added. However, the sound is not there. When I press the lang button on the remote (fortecstar 5600v2) I get on average about 10 audio channels, all of which are AC3, and are not played. Is there anything I can do to hear these audio channels, or anything I can do to add simply the normal sound pid? All the ITV channels have normal sound and are completely fine to listen to.

Thanks for any help you can give
