The current volume slider in the WCM stream is pretty much horrible, as I believe most can agree.
I need to adjust Chrome volume in Win7 mixer settings to like 5%, and even then it's rediculously loud.
The way the slider is designed also makes it very hard to even hit the lowest possible volume.
Any chance this will be adressed anytime soon?

We are looking into it. You do not have this problem at all on Youtube in Chrome?

Nope.

Ok, I have notfied the devs. The volume slider will be improved in next version of the player.

Excellent. :)
