I’m having this problem on an MSI GE63VR Windows 10 laptop.
When I plug in my anker soundcore mini speaker into the headphone port, both the speaker on the laptop and the the anker speaker play at almost the same time but not quite so that there is an appalling echo.
When I try to turn off the laptop speakers
It turns off the external speaker too.
These are the options I have:
When I select ‘headphones’ or ‘Digital Audio’, the external speaker switches off…
No problem at all with the speaker on a mac. Any ideas?
