People I call with Zoiper (Biz 3.14.38765 32bit) complained that my voice is low. So I adjusted the mic volume (as explained here http://www.howto-connect.com/windows-10-raise-the-mic-volume/). But I noticed that when I use Zoiper the Level is forced back to 50%. Even if I slide the mic controller up and down in Zoiper, the level jumps back to 50% in the Windows 10 settings. This does not happen when i use X-lite softphone. Zoiper is pretty much useless now, so I'm using X-lite until this is fixed.
Please try turning off the Autogain control option in your Audio options.
I've tried. Does not work. It stil sets the system mic to 50%
I will escalate your report to the QA team
Could you please share if you are using a USB headset or the integrated audio card?
USB headset. Logitech H820e
I have the same problem, it basically makes Zoiper unusable for me.
