Buzz bought an Amazon Fire Stick and has an old Yamaha Receiver for it, but it doesn't have HDMI. He's managed to connect it, but he gets no audio. Leo says that most TVs have one HDMI/ARC. That's the Audio Return Channel. He wants to plug the FireStick there. But he also wants to also use the optical connection for sound. That's what Buzz did, but it doesn't work on the Firestick. Everything else is fine. The audio settings may need to be changed. Look at the TV setup. Try using the PCM Audio setting.
Adam recently bought an LG OLED 65" TV. But using his Sony receiver with Dolby 5.1, should he plug everything into that first? Leo says that his general standard is to route everything through the AV receiver and then to the OLED. But if he is streaming from the TV itself, he will need an audio return channel (ARC) in order to get that audio through the home theatre system.
Scott Wilkinson recently did an article on how soundbars have the design flaw of using only a single HDMI port. But what if you have multiple HDMI devices you want to connect? Scott was reviewing an LG Atmos Soundbar, when he discovered the drawback. Looking around, he discovered the same problem with other soundbars as well. Leo says you can use Optical, and that makes sense. But Scott says the optical output is limited and doesn't support Dolby Atmos. The only thing that carries the Atmos bitstream is HDMI.
Scott has a question from a user that wants to know how he can run his audio from the TV to his home theatre. He uses the TV's internal smart apps. Scott says that the audio return channel (ARC) that you want to use. This depends on his receiver. Current TVs have this capability. Take the HDMI out from the receiver to the ARC port. That way the sound will come out of the home theatre speakers.
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.
A few questions. Caller is having issues with his ARC in his home theater system. A SmarTV needs to be able to run audio from the TV to the home theater system without latency. That's where AV ARC (audio return) option comes in. But your home theater and TV has to support it. It is essentially sending the audio the other way along with HDMI system. It also needs CEC, consumer electronics control. You also need a high speed HDMI cable, and you have to be sure to plug it into the right HDMI port, which will be labeled HDMI ARC.
Michael has one HDMI port going to his receiver that acts as a kind of switcher. But his antenna goes into coax. Leo says that Michael needs to get a digital box now because nobody really broadcasts in analog anymore. Leo says a TV with digital out could be routed to the tuner, but there will be audio sync issues.
