Volume reduced to 10% on every call

Using a Jabra Pro 830 headset and I also see that the input level of the microphone goes down. In the beginning I did not get it why it seemed when I started to talk like no-one knew I was talking even although I was not muted. This happened then when someone else would just start talking as well.

Then figured out it was my input level on the microphone. Adjust it back up and suddenly people knew. :-) But then it started to happen again.

Well, I watched the input level while in a meeting and talking and noticed it adjusting itself and going down. I think the problem here is that when the call is done, and then a new call is started it starts off with that "new, lower" level as the one to go for. And then brings it down again.

Not sure when this issue was introduced as I do not recall having it in the past.
