Hey guys...new to the forum and have a question about my ota sound. I just upgraded my dish network reciever from the ViP211 to the ViP722...now my fox station (WFXR 27.1) does not have sound....picture is great and my other ota channels work just fine, sound and picture. ive tried switching the dolby options and nothing seems to work....i live in zip code 24141 and use an indoor antenna....any help would be greatly appreciated.
