I'm not here to help (unless you have a faulty optical cable
). I'm just here to mention that I have the sound base version
and don't hear that noise. I replaced it with a similar Yamaha due to sound quality on voice and music, but it was connected by optical most of the time. Sometimes RCA, also fine, and rarely Bluetooth, which obviously sucked.
The sound clip played just fine for me in Chrome, on a Windows 10 laptop. I could hear the clicks on laptop speakers at 100%. Very odd noises - I guess we can't rule out the source til we rule out the cable, or the device. i do have one very thin optical cable, I believe it came with the Yamaha sound base, and it sucks. Some devices won't even play sound through that thinner-than-spaghetti cable. I got another cable that's udon thick, and it's never failed.
Be careful on inserting this (or any G34 chip) into the socket. Once you pull that restraining lever, it is either a good install or a piece of silicon jewelry.
