Why's My Roku App Making Strange Noises!?

TCL

Episode 1837

Rob from Tarzana, CA

Rob has a Roku app that's making odd noises in his Home Theater system. It's part of his TCL 6-series that's hooked into his Denon receiver via HDMI through the audio return channel (ARC). Leo isn't much of a fan of the apps built into smart TVs. They are almost never updated and usually are poorly written. Leo says it sounds like an encoding issue with Dolby. Look in the TV settings (or the Roku Stick settings) and either turn it on (if it's off) or off (if it's on). Set it for PCM and it should fix it. See if that fixes the problem.

Can I Use My iPhone With Google Fi?

 Google Fi

Episode 1817

Ron from Kansas City, MO

Ron is having issues with TMobile and he's thinking of moving to Google Fi. But he uses an iPhone. Leo says that Google Fi works with the latest iPhone, but it'll still be T-Mobile service or WiFi. And it may even be worse as Google Fi service is an MVNO and T-Mobile will likely prioritize their own customers over MVNO service customers. But Leo uses both services and he doesn't really notice it. For Verizon, try Vizbl.

Can I Just Swap Out My TV in My Home Theater?

Samsung QNED QN65Q

Episode 1815

Laura from Goldendale, WA

Laura has a 17x20 living room with a 10-year-old TV that she wants to replace. What size should she get? She's looking at the Samsung QLED QN65Q. Will her speakers be plug-in-play to support them? Leo says yes. Whatever sources they have in the receiver will be supported. She just wants to be sure to plug the HDMI cable into the port that says "ARC." That's the Audio Return Channel, and it'll keep the audio in sync. If the TV doesn't support ARC, then she needs to opt for the optical connection, and some TVs are dropping that. If that's the case, she may need a new AVR. 

How Can I Listen to My TV With Headphones?

LG TV

Episode 1788

Joe from Marlborough, NJ

Joe would like to connect a pair of headphones to his LG TV. But when he does, the volume is very faint. Does he need some sort of amplifier? Leo says that most TVs get their audio from HDMI and the Audio Return Channel. If Joe has a home theater system or AV receiver, it's better to plug into that instead of the TV. What Leo thinks is maybe Joe needs to enable the setting in the TV menu. There are headphone amplifiers. Check out headphones.com for suggestions on which to get. There's plenty of options out there.

Why Isn't My Subwoofer Working?

RCA Connector Cables

Episode 1748

Stan from Victorville, CA

Stan is having issues with his home theater system subwoofer. No bass at all. Leo says that there are two ways to connect your subwoofer.  A single RCA jack or an LFE connection (for low frequency).

But it could also be a setting in Netflix. Make sure you have your Netflix app set for surround. Make sure the highest quality is also selected. Also, check the settings in your streaming box.

Episode 1679

Buzz from Huntington Beach, CA

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.

Should I Connect All Home Theater Devices to My AV Receiver Before the TV?

LG

Episode 1618

Adam from Clairmont, CA

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 ... and the bad solution

Scott Wilkinson

Episode 1606

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.

Episode 1592

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.
