Comment 7 for bug 1575912

Huh, interesting. When I hover my cursor over the sound widgit in my top panel bar, it says:

Output: 100%
0.00 dB
Built-in Audio Analog Stereo

And it says this even when I have something playing that ought to be outputting sound.

Doesn't 0.00 db mean silence?

Reading this now to find out what I can: https://sound.stackexchange.com/questions/25529/what-is-0-db-in-digital-audio -- "So audio meters don't show the dBu, dBV or dBFS level of the signal (some do, but as an extra). Instead they show 0dB as the standard operating level of the system." Oddly fascinating read. I had no idea that decibels were coined in relation to Bell labs.
