SL Music Streams and Windows 10

     I discovered that in the Firestorm Viewer (I didn't try it yet in the SL Viewer), if you've enabled the Spatial Sound (Windows Sonic for Headphones), you might find that music streams in SL don't play the music as good as before. You might hear what sounds like an odd compression, a lower volume, and hear echoing. Disabling this in Windows 10 can improve that sound quality dramatically. 

I cannot be sure if this true on all computer systems, but on mine, enabling that feature did do all of the above.

FYI
