Unable to Activate Recording Signal Via Bose In-Ear Device

I am unable to conjure a signal from a Bose in-ear headset/microphone combination device while using Audacity–the device works fine until I launch Audacity, and then suddenly the signal cuts out. The Audacity recording levels do indicate a sliver of red and I can hear some buzz. I have read all Audacity 's help info on device settings for Windows 8 and have been unable to affect a change. Please help!

Do you have Audacity 2.0.6?

Model number of the headset? Does it connect with a USB cable or pink and green connectors?

Have you tried selecting the USB device (or the external mic if the headset has a pink connector) as recording device in Audacity’s Device Toolbar?
