The sound volume on my ThinkPad T430 has suddenly reduced by half.
I suspect this occurred after the recent Windows 10 update, probably KB4022725 or KB4022405. Has anyone else noticed this effect and if so is there a fix?

After the Windows 10 Major Updates, the Realtek drivers with Dolby Enhancement may be overwritten by Windows default audio driver. Therefore, causing the decreasing volume output from both headphone jack and internal speakers.
Download and install the Realtek driver from this link and the issue should be resolved.
