How do i get speakers and headphones working at the same time?

[foolfromhell]

I go to Audio Properties and I slect Playback and select SB X-Fi Audio and I then select recording and select Plantronics Headset. But that doesnt work.
What do I do?
USB headset and soundcard that goes to speakers.

I'm not sure, just taking a shot in the dark:

USB Headset installs it's own drivers, it's probably over-riding your motherboard's audio.
Or the other possiblity: Why are you selecting record, if you want to listen?
