DAE hear their speakers pop when opening a website with sound?

With my Chromebook connected to an external monitor, and then to an analog audio amplifier, I hear my speakers pop whenever a website starts playing sound.

So I wrote an extension (Endless Whisper) that plays an almost-silent tone in the background, in order to keep the sound system awake and prevent the popping. I assume that 99.9x% of people will never need this, but it's useful to me so I thought I'd share:
