I have had a Tivo Plus for one week. I have lost the sound from the SyFy HD Channel and no others. I have video. I have Frontier Fios and use a Sony htct660 sound bar. I have never had this occur until I hooked up the Tivo Plus. I get SyFy HD on my Tivo HD and on my Frontier STB. I have gone through all the normal channels with Tivo and Frontier. Signal is good at 95% and S/N ratio is 37. I have checked all cable connection, reset the Tivo and had it reactivated, and everything else is great. I use DD for sound and tried PCM just to see if that would work but no luck. I use Toslink for my audio connection and I have tried HDMI. I have my video set at 1080P60 and it works very well. Has anyone else had this problem where just a single channel doesn't work? It does work with SyFy SD. Any ideas?
