My laptop is ThinkPad T480s. I connect it to a monitor through HDMI and an extra speaker. I want to keep the sound to these two devices at the same time. Is anyone know how to achieve it? I have tried stereo mixer method but it failed since there is no stereo mixer in ThinkPad.

Thanks for replying! I am sorry I didn't see the attached image but I checked the Realtek Audio Manager and there is no option as you mentioned(screenshot is attached). Are there any other solutions for my problem?
