Anyone else having audio issues?

Its definitely only within the DotA app. The audio is all crackly and slower than it should be, like as if there's streaming lag. I'll alt tab out and Youtube will be playing fine so its not an issue with my speakers or audio device.

If I got to audio settings within Dota and cycle between 'default device' and 'logitech speakers' it resets the audio and it plays normally, only to go back to being crackly within a couple minutes.
