GScott has a ton of vinyl records and he'd like to listen to them again. How can he connect a record player to his AV receivers without disconnecting his home theater system? Optical out to the TV, and then use the composite connections? Leo says yes. You'll have a setting in your TV that turns on the optical audio option. The turntable he is getting will have a preamp in it as well as a USB to capture. Leo says that as long as the audio is balanced by a preamp, it'll work just fine.
Larry has 12-year-old florescent backlit TV and it's time to upgrade to 4K. It's in a surround sound system with a Denon receiver and he would rather not upgrade that as well. Leo says there is an "upgrade cascade" that happens when there is a home theater system. If an AV system drives video, then users have to upgrade it. But if it's just running the audio, they'll be fine. Just use the optical out on a new TV. Upgrade the ROKU box to 4K capable. But what's even more important is the HDR support 4K brings.
Vino wants to know if he can delete the apps on his Roku box. Leo says to click on the asterisk and select the app, and he can delete them from there.
Bernie wants to know if HDMI is the same as optical for audio quality. Leo says that both connections are digital, so it's the same quality. Optical will give him Atmos and other multi channel stereo options as well.
Peter switched from one satellite company to another. On his old satellite receiver, he had an HDMI output he could run to his TV and RCA audio outputs that he could run to his outdoor speaker system. his new unit no longer has the RCA audio output. It has an AV Out, a 1010 round port, and a digital audio out. How can he convert the audio? Leo says he can get a little dongle that could convert either the digital audio out or even from the HDMI out. He would need an adapter that will strip the audio out of it.
Kent bought a sound bar for his older Samsung TV. He uses a Chromecast and Roku Stick with it, but he can't get audio to work. Scott Wilkinson says that the optical out for the old Samsung is probably only for the TV's internal tuner since it's older than the advent of streaming media. There could be a setting in the menus, but he's better off going with HDMI input.
Ryan connects his sound bar to his TV through the headphone jack and over time, it gets harder to hear. He can have it turned up to 90% and it sounds like it's barely on. Leo says that he should try changing the sound on the TV, not the sound bar. It should raise or lower it.
There may be a setting in the TV's sound settings to treat it as a line out. That could fix it. Connecting to the optical jack is the solution, if he can, because it's a fixed level.
It doesn't matter, the sound will be the same either way because they're both digital. He'll just want to be sure he's getting the Dolby 5.1 signal into the sound bar properly.
