Okay, so, whenever I talk on mumble my voice output to everyone else it seems fine. But, as soon as someone else talks, my voice get drowned out and lowered as if they have priority over me. Now i no there is no setting for that and i have played around with my settings to see if anything could help but nothing did. I eventually reverted back to my defaults. Is anyone else having this problem too or is it just me because in the server its only me.
under Settings -> Advanced -> Audio Output . Try changing the "Attenuate Applications By...." setting. Untick the "While Other Users Talk" setting, and see if that helps
