I've got Zoiper 3.6 installed on two Windows 10 PCs. Both installations are the pre-configured SIPGate versions.
On my laptop Zoiper works perfectly.
On my main PC use a Smart TV for display and sound via a direct HDMI connection from my graphics card.
The Zoiper installation on the main PC registers and can make and receive calls, but I don't get any sound output. Even the Zoiper audio wizard fails to output any sound on either the Microsoft sound mapper option, or the HDMI connected TV.
This doesn't seem to be a software configuration issue.
Other applications can output sounds perfectly. Is Zoiper unable to output to audio certain hardware devices?
Any idea what's going on?
