Vizio sound bar as PC Speakers

[davealeb]

I am going to get the following vizio system:

I am reading around that there is a possibility of using the vizio system as pc speakers at the same time they are used as a TV sound system. How is this possible.

Could someone explain.

Thank you!

the speakers has more than one input.
hence tv goes to one input, pc goes to another input. both inputs at the same time.
