Q I have a modest home theater in my basement that I have been slowly upgrading over the last two decades. The only component I haven’t upgraded yet is my Polk Audio subwoofer since it was a pretty decent model when I purchased it 20 years ago. Would I benefit from upgrading to a new 12-inch sub? —Cal Rempel, via email

How Do I Get Dolby 5.1 from My TV’s Streaming Apps to My Old Receiver
Al Griffin  |  Feb 27, 2020  | 
Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com

Q I’m using the built-in apps on my Sony XBR-55X850C TV for video streaming. The set’s optical digital audio output is connected to an older Denon AVR-4306 receiver. My problem is that I only get Dolby Digital 5.1 sound from the TV’s Netflix app; no other app (HBO Now/Go, Sony Crackle, Hulu, or Disney+) provides DD 5.1. My local AV shop suggested using another streaming device or upgrading to a high-quality optical cable. Any advice or suggestions? —Ken Ashlock, Colorado Springs, CO

WTF! Why Don’t All Streams Have Gapless Playback?

Q I just finished listening to the new Giles Martin remaster of The Beatles’ Abbey Road via a 24-bit/96kHz stream from Qobuz. For the first few tracks I felt like I was listening to the original album, but on a much better stereo system. Then the bad news came when I got to the medley on “side two” starting with “You Never Give Me Your Money.” Instead of a seamless flow between songs, I heard distinct gaps between the tracks. It really ruined the experience. Why can’t streams of album tracks that are supposed to segue do so without annoying, and at times jarring, gaps in the sound? There are lots of iconic recordings with the same issue. —Thomas E. Moore, Fairfax, VA
