Thanks . Every thing sound related is shown as working properly.
After a lot of fiddling and far**ng around I have sound, but only through headphones.
I tried the instructions below but there is no option to change output. It's set up for external speakers.
Its only showing that one option. I tried disabling it and that didn't work.
Type and search [Sound settings] in the Windows search bar①, and then click [Open]②. In Sound settings, you are able to choose the Output device③ (such as internal speakers, external speakers, or headset) and the Input device④ (such as internal microphone, external microphone, or earphone).
