I have a Tivo Roamio Plus and I just started having audio issues when watching anything on any of the apps (Amazon, HBO GO, Netflix, etc). The video plays just fine but the audio sounds like a helicopter. The sound is just fine when watching live TV or anything that I've recorded. I've restarted it, unplugged for a minute and powered back on, and still it didn't make a difference. The only other thing I can think of to try is to do a factory reset and I really don't want to do that and lose all of my recordings. Any ideas or help would greatly be appreciated. Thanks!
