Multiple instances of Mumble - Volume goes to zero

[valhalla]

I have a setting that reduces volume by x% every time someone uses the mic.

I have isolated the cause of this to Mumble itself because I have disabled the windows setting to do this.

The problem is that when I run multiple instances of the client, the volume reduces from 50%, then 25%, then 12.5% etc. Possibly because people are speaking on both servers, and the client does not register that the person is not talking anymore and restores volume level to 100%.

Over time my volume goes to zero and I have to manually reset it in the volume control panel. This is very irritating. Please fix!
