Is your connection stable enough, but are you still experiencing audio issues? Check the settings of the headset you are using.
Make sure you do not select the "Default" or "Communication" devices, but the device itself. If the settings are set to Default and Communication, your operating system may switch itself off, causing you to suddenly make calls through your monitor without speakers instead of your headset.s.
Is everything set up correctly? It is possible that the audio is being blocked by your own network.
In that case, try the following:
- Restart your router.
- Are you using WiFi? Use a LAN cable (possibly with a hub as an intermediate piece) in your laptop. This will make your internet connection more stable.
