Default [Q] In call volume at 50%

Hi there.

Any time i start or receive a call in call volume is automatically set to 50% and I need to increase manually.

This is very annoying, overall using an headset.

Anyone solved this issue?


PS: performing sound adapt seems to fix calls with earpiece, nothing to with headset...
