Answer 2

You need to install drivers for the hardware that has yellow exclamation marks by it.



Usually Windows update will get you basic working drivers but you're better off going to the manufacturers website and looking there.



If your sound card is built into the motherboard then the motherboard manufacturer will have the drivers you need for the sound as well.

Answer 3

Wow I dont know what all that means but



check your speakers connections

and the check all the volume controls

you would be surprised how simple the problem can be

Answer 4

it seems to me that your computer does not have the proper audio drivers, it cannot say what the Audio device is, and i would assume that you are either missing drivers or you drivers have been corrupted somehow.

Answer 5

that tells me to turn your speakers on or get new ones.
