Speaker cuts on calls - works fine otherwise

[Ashfield Hill]

Hi. We use Jabra 9450s and up until about three/four weeks ago all was fine (have been for a few years); however, all of a sudden, half of my headsets cut volume when a call connects. The speaker sets work fine with all other PC volume duties, as you make a call you can hear the ring, but then all goes silent.

We've found that if we ‘reset’ the 3cx audio setting (doesn’t matter if it correctly says Jabra headset or not to begin with) and shut down (not restart) the machine in question then all works fine for the day, but it’s a gamble on the next boot up.

Any thoughts/guidance, please?

Hello

try to take a look on control panel>sound>communications> there is a strange mute setting - try to disable it.
Hope this helps
