A:Answer TBH this question doesn't seem to make a lot of sense to me, because this is a set of speakers and so is the soundbar. Well, if you mean, "can I connect the soundbar so that sound is coming out of both the PC speakers AND the soundbar", then well.. mainly no. At least, you can't connect the sound bar to the PC speakers. You could, however, get a 3.5mm splitter "Y" adapter and split the audio coming from the computer and run an output into both sets of speakers.. sure, you could do that.
