Scott, do you know what kind of speakers will work with an PC? How many ohms should one look for? I ask because standard speakers don't seem to work with the HP SignagePLayer mp8200 PC my dad bought.

The green "speaker" connector on a PC is not really a speaker connector after all, it is a connector. As such the power output levels are extremely low, incapable of driving speakers directly. The low power signals from the Line Out connector are designed to be connected to the Line In connector on an amplifier, which provides the amplification and higher power output necessary to drive speakers. In other words speakers are connected to an amplifier, which is then connected to a PC.

Note that the "speakers" normally sold for PC use aren't just speakers as they also include a built-in amplifier. If you have speakers with a built-in amplifier then you can connect them to the Line Out (green) connector on a PC. On the other hand if you have plain speakers then you would connect them to a compatible amplifier, which would then be connected to the Line Out connector on the PC. Scott.

Keep in mind that even when external speakers are connected to the PC in question, the system's internal speaker doesn't shut off. I tried a set of external speakers with both of the PC's speaker ports a little while ago. Sound did come out of the external speakers, but faint and distorted sound.

No offense, Scott, but the system in question doesn't have a slot for a spare sound card.

That's too bad, I've found that integrated audio is very failure prone. I've had to disable the integrated audio and install sound cards in many systems over the years. Hopefully in your case the problem lies with the speakers. Let me know what you find, Scott.
