My VON volume is stuck at one level.
The VON slider doesn't adjust the VON level any more and the volume is very high.
This affects all the different channels, direct, group, vehicle etc.
This happened after the latest patch to the game, and as I can read in the forums I am not the only one affected by this bug.

I have tried reinstalling ARMA completely by uninstalling the game, deleting all folders and profiles before re-downloading the game again, but the problem remains persistent.
I also removed all audio drivers and reinstalled these but to no avail.
All audio devices that is not in use is also disabled to avoid any conflicts there.
