Ed is having problems where the volume in his Vizio soundbar changes audio as he changes the channel. Leo says it sounds like the IR from the Verizon FIOS box is merging the two commands and passing a volume command to the soundbar. There are only so many IR codes, so it's possible the confusion is causing it.
Gloria watches TV on her phone but she's not happy with the audio on her Google Pixel 2. Leo says it may be related to what Leo was talking about with surround sound. Many phones are in stereo or mono and as such, the audio is problematic since most TV and movies are mixed for surround sound of movie theaters. As such, the soundtrack gets "mushed" together.
One solution is to get a Bluetooth speaker and use that to listen. They can connect wirelessly and give much better sound than the speakers on mobile phones. Headphones would also work.
Scott joins Leo to talk about the Helm Audio DB12 AAA pocket headphone amp. It uses THX amplifier technology. Noise measurements are far lower in total harmonic distortion than any chip-based amp. And while the price of the DB12AAA is $200, it does make a huge difference in audio from a mobile device. But since mobile phones have eliminated the headphone jack in favor of Bluetooth headphones, users would need an adapter to use it.
Vince has a Sansui receiver from the 70s. Can he still use it with his home system and his Pioneer Elite Plasma TV? Leo says to check out ClassicReceivers.com. It really comes down to the output. He won't be able to use it for video, though because of the HDMI connectors. He can get a device that will take the audio portion and route it to the old Sansui device.
John is noticing that the audio when he watches streaming TV is starting to get out of sync. Leo says it's not uncommon. But since he can watch the same TV on other devices, it's likely the TV. Look in the audio settings to adjust the sync. Check the cable. He can also try changing the audio encoding. Make sure the effects options are off.
Lance wants to listen to alternative audio on his TV while watching video. Leo says that if you're connected via HDMI, the TV will play both automatically. The only real option may be your AV receiver, but that's likely going to do the same thing. Component out might work.
Jeff has seen old time radios that have had a bluetooth receiver put in them so you can use them as a cool, retro bluetooth speaker. Leo says those a really cool idea. Is there such thing as a bluetooth extender? Leo says there is, but bluetooth is designed to be short-range. WiFi is a lot better and has five times the range. There are plenty extenders though that boost the range. Miccus makes a bluetooth extender with 160-foot range for $40.

Steven recently heard aboutHeadsets. How are they? Leo says that they use the same technology as the Bone Phone from the 70s, but better. It transmits the sound through the bone just below the temple. It promises hi-fidelity that's as good as earbuds or better. It works great for sports, driving, or anything where we can't have our ears blocked. They're bluetooth with good battery life. Leo can even use them to make phone calls.
Max is having issues with his TV speakers on his Vizio D series TV. He keeps hearing audio coming out, even when it's off. Leo says that today's modern TVs don't really turn off anymore. They just go into a very low power mode. Leo suspects that Max's Xfinity cable box woke his TV up through HDMI. Leo recommends putting the Vizio into Eco mode and it will turn off. Then, he should turn off CEC in his TV settings.
Scott is back from CES and this week he wants to talk about the audio gadgets he saw. A lot of the high end audio was at the Venetian Hotel. But Scott says that audio had a much smaller presence at CES this year, and Scott thinks that audio companies are going to be going to regional shows to offer their goods rather than spend a ton of money at CES. And it's difficult to rise above the noise at a larger convention. Smaller, regional shows offer a big fish in a small pond kind of vibe.
