On occasion I like to play Dota2 with music playing, instead of ingame volume. I'm sure there are more than me who does this.

I have one problem though; if i mute all sounds, then everything is working good. But then I won't be able to hear people using the in-game voice communication tool.

So to solve that, I turn music and and game volum all the way down. Let master volume and Voice volume stay max. And that's where I get a problem.

I hear more sounds than just player voices. I hear the sound when I respawn. I hear pre-game sounds etc.

This probably isn't high prio, but what about making two sliders? One for NPC-voices, and one for human voices only? That way you can have the option to only listen to in-game voice communication, and nothing else.
