Installed USB Headset/Microphone...Now No Audio!!

I can't seem to get my audio working ever since installing USB Headset/Microphone. I get audio via my speakers...as well as audio via new headset device. I can get audio to listen to music. Problem is through Reaper. It keeps telling me to check my audio settings. I checked in the audio/device manager, and tried various settings, and still nothing via Reaper!! What I want is for the new USB headset to handle all audio through my system. Thanks in advance for your help. Matt

Have I missed checking a particular setting, or something?

post a screen shot of the audio device settings. The device may not be able to run at 24 bit

I'm sorry, but I don't have access to a camera right now. I'd be happy to answer any questions in ref: to the audio settings. Thanks...\m/ \m/ Matt

The Error says..."Error Initializing Buffers"

Just so you know, and I should have mentioned this but, I use a DigiTech RP-155 Modelling Processor via USB, and I currently run my other Head phones through this.

My new Headset returns audio when I change the audio settings to "Direct Sound" or "Wave Out" from ASIO...but my other Headset stops working. I just want to get my new Headset to produce all of my system audio.

It's just a LogiTech H330...Nothing major.

Maybe I said this wrong, but have been using ASIO via the Digitech, and it had been working, until I plugged in the Headset. Like I said...in order to get things to work, I have to switch things around in the audio device menu. When I first got my DigiTech about 2 years ago, I plugged it in...and it worked without any adjustments whatsoever. Now...at that time I was using Audacity as my DAW, but Reaper was just as fast with the recognition of my DigiTech. Basically, when I try to play my projects like I always have, I get that error message. When I switch to say..."Direct Sound." The input/output device says "DigiTech RP-155, but I have to switch to my headset to hear it. When I go back to my original settings, no audio, and I get that "Buffering" message. I will try ASIO4ALL, and see what happens. Are there any detailed settings on ASIO4ALL that I should make sure I check? Thanks... Matt

It says on the input and outputs "Not Connected." I connected the devices on ASIO4ALL, but it still shows "Not Connected" even though the driver says ASIO4ALL. Hmmmmmmmm???
