I have just purchased Zoiper 5 (osx Mojave) and no matter what I select as input device (it shows them all ) there is NO sound reaching Zoiper... meters simply dont move when trying ALL my input devices...all other programs work fine, Skype for example...
It doesn't even work with the MacBook Pro internal mic...
Can you please urgently help , as the product is currently useless with no input
Many thanks
