Have watched black mirror episode 2 / season 6 on Netflix.
The series is not my big favorite but not boring to me and watched all the episodes so far.
To watch the video “silently”, I tried to use my earphone but looks it can work well with bluetooth USB adapter on windows10.
I tried to solve, but couldn’t find any solution.
Trying drivers, using different USB ports, trying to find change bluetooth codec on windows10(but actually this is not possible).
Anyway I gave up and started to use wireless head-phone, so no issues from the beginning if I just chose this option.
But each option can be chosen with or without the reason, and this kind of thing can happen anytime at anywhere.
