Sound cutoff when someone speaks.

[Guthy]

So today I purchased the WoW headset which is a really big upgrade from my previous one. But soon i discovered that when someone talks in vent, just the second they use their PTT button it shortly interrupts my music or whatever else is playing. It is very annoying especially with more than one person in vent because it is as if the sound for my music mutes for like .5 seconds then starts playing normally. The volume doesn't lower when someone speaks it just has this short cutoff.
