Headphone Audio Driver - Acer Swift3 SF315-52
I have a new Acer Swift3 SF315-52 laptop; the speakers work fine but I get no sound out of headphones when I plug them in.
Under "Audio Inputs and Outputs", it shows "Speakers (Realtek High Definition Audio (SST))" installed (version 10.0.18362.1); the icon shows "Speakers" and not "Speakers/Headphones". Intel Microphone Array and Realtek Stereo Mix software are also shown.
Under "Sound, Video and Game Controllers", it shows "Realtek High Definition Audio (SST)" installed (version 6.0.1.8555); again there is no mention of headphones. Intel Display Audio and Intel Smart Sound Technology software are also shown.
Device status shows all 6 programs are working properly.
Do I need to download a driver specific to headphones or a driver for "speakers/headphones", and if so, from where? Do I need to disable or uninstall any of the above?
