I have an older Romario OTA that works well. Today when I turned on the TV, there was no sound. The picture and everything else seems to be working fine. the tv is fine, I checked cables and inputs, even switched them. Reset the TiVo more than once both internally and by unplugging it. I changed the sound setting in the TiVo from one to the other and back again. TiVo is connected to the TV via HDMI. My tv doesn’t have an optical in, or I’d have tried that. I am stumped. Any help would be appreciated.
