Volume slider is broken, but needs to be moved to start the audio.

[NinjaGeoff]

Okay, so the title may be a bit hard to follow, but here's what's going on:
When I go to the webpage in Chrome I see everything as expected, but there's no sound. I click/tap (behavior is the same on my desktop as it is on mobile) the volume slider and suddenly there's sound. Also, tapping the volume icon, or moving the slider all the way down, only lowers the sound ever so slightly. Again, same behavior on mobile as on my desktop

Firefox on my desktop audio starts immediately, but the volume slider still doesn't do much of anything.

Both I'm loading in incognito/private mode to skip my plugins/extension.

Now, here's the really weird thing about mobile. If I minimize Chrome, switch to another app, or even lock the screen, the sound still comes through, though that works for me as I'm really using it to keep an eye on my dog and make sure she's not barking and bugging the neighbors.
