Microphone power under Windows insufficient

Due to the positive assessments I have ordered with the Jabra Speak 410 on Amazon. The start-up was easy, but then came the disappointment. On Windows, the microphone power is simply insufficient, and at highest level. Directly supported programs (in my case I was able to test it with Skype and Bria 3) have this problem strangely not, but those who rely on the Windows driver (a special driver from Jabra, there are neither supplied nor on the Jabra website ). In my case, that's first of all the SwyxIt client that I use frequently, and "suffering" in its application the interlocutor at the other end. A reply from the Jabra support brought confirmation that there is no solution to this problem, therefore, a good piece goes back. The second point I forgive, because it certainly does a good job with the above restrictions for supported applications.
