Please clear it up about sound settings for adapter to pass audio (given that my MBP mid 2010).
I've bought some cheap adapter and the picture is ok but there is no sound.
In the shop they said it should work.
When I open System preferences - Sound - Output - all I can see is Internal speakers and that's it. Nothing I can do there.
How can I add another device or what should I do?
Thank you in advance!
