I have been using Zoiper 3.9 on my laptop with a Logitech G35 headset for several months on Windows 7. I recently upgraded to Windows 10 and now Zoiper does not work with the headset at all, either the speakers or the mic. No sound what so ever.
It still works with the laptop speakers and mic, but those are not ideal.
I can also get other Voip apps to work (X-Lite, Skype, Bicom gloCom) without any difficulty.
I made sure no other Voip apps were running in task manager, and even shut down the Logitech gaming software, just in case, but nothing has helped.
I tried re-installing Zoiper, still nothing.
Any ideas why it would have stopped in Windows 10? I saw the posts about there being no issues, but it stopped completely for me.
