4. Avoid Transceiver Interference
If you have your transceiver located at the back. Move it to front USB slot because we want to avoid any interference. Even though placing at the back on Windows 8 or Windows 7 works great, it would not promise that it will works on Windows 10.
5. Update Graphic Driver with Latest Version
Default driver provided by Microsoft (along with Windows 10 installation) could be the reason for the lag. Go to the manufacturer website and download the latest driver version available. Updating using Windows update is not recommended. For Intel graphic, installing previous version reported resolve the issue.

for conexant it located in
c:\program file or Program File(86)\forteconfig\

The other thing is to remove forteconfig in add remove program in control panel. ForteConfig commonly found on Lenovo notebook which installed along with Conexant Audio Driver software installation.
