the digital to analog conversion with its built-in sound card and outputting an analog right and left channel audio signal. This would be connected to the CD or AUX inputs on the receiver NOT the digital input on the receiver. Also you mentioned quote, “jumpered main in and pre out for the front speakers using male-male RCA cables” why are you shorting these connections? You should only need the cable from the netbook computer plugged into the analog CD or AUX inputs on the Harmon Kardon AVR 20-II receiver and then speaker cables from the receiver's speaker output jacks or 5 way binding post connectors (whatever that receiver has some are just cheap spring clips) and then to the right and left speakers respectively. Make certain that the receiver is set to the CD or AUX source selection whichever one you connected the cable from the netbook computer to.

Additionally you wrote, “speaker wire (bare wire) going from the speakers to the front speaker hookups on the receiver” I hope you meant that only the ends of the speaker cable are bare wire connected to the speaker out binding posts on the receiver, the length of speaker wire itself should be insulated or else there will be a dead short between positive and ground and will fry the output transistors on the receiver.

Thanks for the ongoing help!

The RCA ends of the cable are plugged into the CD inputs on the receiver.

The manual says that you need the jumpers if you aren't driving the speakers with an external amp. Since I don't have the jumper plugs, I'm using the RCA cables (suggested by an online source).

Make certain that the receiver is set to the CD or AUX source selection whichever one you connected the cable from the netbook computer to.

Definitely set to CD.

I'm bad, but not that bad! Bare at the ends.

  You need to find out if there is a signal coming out of your computer. Plug some headphones into the computer and see if you hear anything. If the computer is working correctly then your problem is in the HK receiver. Make sure the tape monitor switch in not engaged.
  
  Again, thanks.
  
  I did test with headphones, which is why I ended up having to download some new drivers. That now works fine. Tape monitor switch is off.
  
  Sigh.

    Since you're using a receiver, check to see if the tuner produces any sound from your speakers. If not, you've got problems in the receiver.
    
    If you can connect your headphones to the preamp out that you've connected to the front amplifier input with male-to-male RCAs, it will tell you whether the problem is in the preamp section or the amplifier section of your receiver. In other words, disconnect the male-to-male RCAs and see if you can use an adapter to connect your headphones to the preamp out. If you don't hear anything in the headphones, then you are not sending a signal to the amplifier section of your receiver.
    
    Good luck,
    John Elison
