I'm pretty sure you need to adjust the "chat mix" knob on your headset as the audio will now be playing through a separate audio device on the headset. Basically previously it was using the mono "chat"/mono output on the headphones. Now with the ppa it's primarily using the "game"/stereo output. AFAIU the knob adjusts the mix between the two outputs on the headphones themselves.
