The other day when I was in vent using my head set i had to unplug, upon doing so I started getting

"createsoundbuffer error unknownrun_20_4"
"createsoundbuffer error unknownrun_20_5"
"createsoundbuffer error unknownrun_20_8"

with every step.

Can someone with a USB headset test this and tell me if it happens to you also? Simply run the game then unplug or plugin your headset.

Thanks
