Audio Delay on Call Pickup 3CX Desktop App

[LanceK]

Hello, hope you're doing well.

I am having an issue with one PC having a 5 second delay between when the call is initiated and when audio is sent/received. The delay is the same length every time incoming or outgoing and the issue is only occuring on one PC and only with the 3CX app, I configured a different Softphone (MicroSIP) for testing and the issue was not present then. The user is currently using the mobile app instead due to the delay and they are not having issues there.

I am using Version 18.8.508 of the Desktop App, the issue occurs if I use a different extension on that PC, I've uninstalled and reinstalled the 3CX Desktop App and audio drivers, setup a different extension on the PC and created a new user profile on the PC and the issue repeated itself.

The PC specifications:
OS: Windows 11 Pro
Make/Model: Surface Book Pro 2
RAM 8GB:
CPU: i5-8350 1.9ghz
