Bluetooth mic barely audible, Intel Centrino 2230

My Intel Centrino 2230 dual-function Bluetooth card is built into my GIGABYTE GA-H77N-WIFI LGA 1155 Intel H77 motherboard. Upon updating all Bluetooth & Wi-Fi drivers (all-in-one card), I was able to get my VXi BlueParrot B250-XT+ to connect as a VoIP headset. There's one major issue, however: the input is incredibly distorted and low-level. If I yell through the microphone I hear a buzzing noise, but otherwise the output from the speakers is virtually silent. This is all with the microphone gain maxed out. Turning the gain down does nothing but silence the microphone entirely (I understand why). I tried to talk to my sister over Skype, and she said that she heard low-level distortion and nothing else. This headset works well with my phone, and has no issues pairing with the PC or phone. Whatever it is must be in the PC. I tried a USB Bluetooth dongle and was able to get great input from the microphone, but then the dongle stopped working. The adapter simply just quit. This was not due to interference from other Bluetooth equipment or software, as neither was operational while the dongle was installed. I would very much like help with this issue, as I purchased the motherboard with the intent to use the on-board Bluetooth, and it seems that USB Bluetooth dongles just don't last, based on my experience and the experiences of reviewers across the 'net.

Thank you for any and all assistance with this issue!

By device, you mean the headset? I have powered it down with the multifunction button, and attempted to pair it more than once to the computer, all with the same results. There is really no way for me to reset the headset, as there is nothing to really reset.
