I've never had this issue before. I googled and found people with the problem from 2010, 2013, 2015 and one post from Jan 2018 (without a resolution). I've had 2 shows I tried to watch today that don't have sound. I first tried to watch them on my TV and found no sound, then I tried the iPad and also found no sound. I am located in Texas. The 2 shows are on different networks. ABC - 2/1/18 TNT - 12/19/17 These are 2 shows out of many that record. I've never had an audio issue with live TV so I don't know if there was an issue during these times or not. As mentioned, this has never happened before on any of my Tivo boxes (currently Roamio). Thank you in advance if you have any idea how to get the sound restored or if you know it's a lost cause and I just need to buy the episodes missing sound.
