Why don't my headphones work with my home theater system?

Optical splitter

Episode 1541

Eileen from Upland, CA

Eileen bought a Bose sound system, which is connected to an optical splitter, so they can use her headphones too. But now the headphones won't work after a power surge. Leo says it's possible that the power surge fried the optical splitter. She should check if the headphones work with her TV (she may need to change her audio settings in the TV). It may also be possible that the settings changed in her TV, so she should look in there and see what it's offering. She may need to reset it to PCM unencoded audio or something similar. She should just try different settings.

Scott got an email from a listener who wanted to stream using an old analog receiver and speakers, and Synology NAS. Scott says that the listener discovered that using the Chromecast audio (which has an analog/digital output) was the ideal solution. It works great with a powered speaker or a pair of speakers which are powered by the AV receiver. You have to set it on AUX, but if all you have is analog, this is a great workaround.

Why can't I get sound out of my TV?

Al from Roseburg, OR

Al has an old receiver and he wants to connect his TV to it. He bought one, but he's not getting sound from the TV. If he connects it to the Blu-ray player, though, it works just fine. Leo says that he'll need to go into the LG menu setup and disable the onboard speakers in favor of external speaker output. Another possibility is the DAC may not understand the TV signal because it's encoded, while the BluRay Player is using unencoded PCM audio. Al should figure out what audio the Blu-Ray is sending out and see if he can duplicate that setting on the DAC.

What is the difference between OLED and QLED? Scott says that OLED is Organic Light Emitting Diodes, and is based on organic chemistry, or carbon. That's how it makes light. QLED, on the other hand, stands for Quantum Dot Light Emitting Diode, and it's just a higher end LCD TV. The light source behind the panel is using quantum dots, including LEDs to illuminate the image. They are completely different technologies. But the "QLED" term confuses people, and they may think they're getting a special OLED screen, but they aren't.
