Can I Hook up my PC Speakers to my TV using this Method?

I'm fairly certain this would work, depending if the Altec Lansing PC speakers have a mini stereo output to connect via the adapter. Also are the speakers powered by the computer (passive) or do they have a plug of their own (active)?

Whoops sorry for late response. I dug up an old pair of speakers that came with my old Dell machine and plugged them in via adapter, and I am getting a pretty significant increase in range. Although it cannot go as loud as it did before. But I keep my volume pretty low anyway.

Thank you and consider this topic closed.
 
what adapter would you use to hook dell altec lansing 5.1 speakers to a tv. i am willing to buy a receiver to make the surround sound work if it is possible.
