George FaceTimes a friend in Australia and lately he can't see his video stream. Leo suspects it's a bandwidth issue on the Australian end. That's a long way, and there's latency issues and more. He should have him check with his ISP to see what his bandwidth is. He may need more for HD video.
Naomi has a Ring doorbell and wants to know if she can back up the video and images to her NAS. By the time she gets the notification from it, the person who rang the doorbell is already gone. Leo says she could Live View it. Leo suspects that Naomi may have a bandwidth issue with her ISP. Ring goes to the Ring servers before contacting her, so there's probably latency in her network due to being in a rural area. Leo says a motion sensor camera could ping her faster than Ring.

Ken wants to know why he can't hear himself when he speaks with headphones? Leo says he'd need a mixer that can mix in. It's called Side Tone. It can be very distracting with Bluetooth on a phone though because of the latency. He would just end up getting confused by the echo.
Harvey wants to get a sound bar for his TV so that dialog will be easier to hear, but his TV doesn't have any analog output. Leo says that since HDTVs are all digital now, there's not much of a reason for manufacturers to put a digital to analog converter inside. The good news is that most sound bars have digital inputs. Harvey already got a J-Tech Digital to Analog Converter.
Jill wants to find an app where she can record herself playing a few different instruments and then play them all together. Leo says there aren't many apps for audio recording and play back on Android because of a massive latency bug. Leo believes it's in the kernel, and they haven't fixed it yet. She can find out more about it at superpowered.com.
Mike just bought a Sony Bluetooth over the ear headphone set. Can he use it with his television? Leo says he can get a Bluetooth transmitter, and if his TV has a headphone jack, he can just plug it in and then pair that to his headphones. He should look for A2DP because that has the best quality audio. Analog could cause a bit of delay, though. That's why keeping it digital is important. If there is delay, Mike can possibly adjust it in his TVs audio settings.
Manny set up Karaoke in his house through his computer, but he's having lag issues. Leo says that the best way is to buy an all-in-one Karaoke box, as they're pretty cheap these days. But if he doesn't want to have that extra expense, Leo says there will be lag when plugging a mic into an analog jack. It won't be much lag, but it'll be enough to drive him a bit nuts. Leo suggests using different software that can compensate for that. Manny should try PCDJ.
Paul is frustrated because his audio is out of sync with his video. Leo says that's a common issue because audio is much easier to compress and decompress than video. But Paul says it gets out of sync with his wireless Bluetooth headphones only. Leo says that's a latency issue. Wired headphones would likely solve the problem.
John takes music lessons on the internet to play the harmonica. The teacher uses Adobe's Meeting, but he has extreme latency issues. Leo says it could be hardware, but more likely it's the ISP's data flow rate with Adobe. It's causing a delay from Adobe to John and back. Leo suggests doing PingTest.net to see what the latency is. If it looks good, then the problem is with Adobe.
Roger wants an HDTV that he can use for gaming, and he needs it to have low latency. Leo says that the key feature is response time. Old style TV sets had a response time of virtually zero, which is why they're still the best option. LCDs are about 4 milleseconds, which isn't bad, but it does give some motion blur. Latency has to do with connectivity. If he can turn off processing, he'll get better performance.
