Please post the make and model of your equipment so that someone can offer helpful advice.
If your PC has an HDMI output, then you should be able to hook it up to an HDMI input on your audio system and listen to Pandora.
First, let's start by confirming that I'm an electronics dope, so please talk real S L O W.
When I had my TV system, tuner, etc installed the technician said I'm going to set up this HDMI connection in case you want to hook up your PC. Well, I'd like to use my PC and the HDMI cable to listen to Pandora through my surround sound. Can I do so??
Thanks for your help.
