A:Answer 1. Since most PCs have a mini jack for audio output, and the soundbar has rca audio inputs, you would need a cable that has a mini plug on one end and rca plugs on the other. These are available at most electronics stores and departments. 2. Otherwise, if your PC has an optical audio output jack, you could get an optical cable since the soundbar has that input jack as well. Then press the input button on top of the soundbar for the proper input. 3. Or, if the PC has Bluetooth output, you can use the Bluetooth input on the bar. Hope this helps.
