Q I’m ready to upgrade my surround sound system to a 5.1.4 Dolby Atmos configuration. My current 5.1 system uses GoldenEar Technology speakers, which I want to keep. Here’s my problem: I have no way to run wires through the ceiling to mount in-ceiling speakers, and I don’t want to deal with the unsightly wires that an on-ceiling speaker installation would require. Here’s my question: Are there any wireless speakers I could use for my Atmos upgrade? —Michael Henn

Q Do you know of a good solution for streaming audio from a Windows PC to B&W P7 wireless headphones using Bluetooth? Is there some kind of USB adapter? —Robert Prinz

Q Should I use the quartz lock feature on my Audio-Technica AT-LP120 turntable? I don't see or hear any difference when I press the quartz lock button. Same thing when I press the +10 /+20 pitch control button. FYI, I usually play records with the +10 pitch option selected. —Josh Rosenthal

Q I'm slow to bite on buying an Ultra HDTV because I’m waiting to see which high dynamic range format will stick. If I buy an HDR10-only set and Dolby Vision wins, can support for that format be added through a future software update? —Ray Blackburn

Q I bought my Samsung UN65JS9500 Ultra HDTV back in 2015.  According to Samsung, it supports high dynamic range. However, when I browse the Netflix app on the TV, the listings will indicate if a program is 4K/Ultra HD, but not if it’s high dynamic range. I’ve asked both Samsung and Netflix tech support what the problem is, but have yet to receive a clear answer. Can you help? — Jon Fraser

Q I'm big into home theater and computers, hobbies that naturally consume lots of electricity. Now that my AV receiver and TV are both due for replacement, I'm hoping you can recommend “green” products that will give me the same great experience, but without the ding on my energy bill and the planet. —Justin Nealis

Q My audio setup consists of a Yamaha RX-A3030 receiver, M&K speakers with 2 Paradigm front effect speakers, and a Velodyne sub. Although I’m in my late 70s and have trouble hearing high frequencies, regular TV broadcasts sound clear on the system. Movie dialogue, on the other hand, sounds muted and is difficult to understand when I watch DVDs or Blu-rays. What steps can I take to make movie dialogue match what I hear with regular broadcast TV? —Bill Vandervoort, Chanute, KS
