Hi, I need advice.

Equipment :

1. AEGO M System 2.1 Computer Speakers (1 pair of RCA line-in jacks)
[best there is under USD150. You name it , I had auditioned it --> Logitech, Altec, Klipsch, Edifier , etc]

2. TV with a pair of RCA line-out jacks

3. PC

4. CD Player + integrated amp (with a pair of RCA line-out jacks)

Only 1 Objective :

Through the AEGO, listen to TV (if it is on), or/and PC, or/and CD Player. That is,

a. if I am watching news on TV with the CD player playing - I can hear both through just the speakers.

or

b. I am listening to the news on TV, music from the CD Player, and any audio coming out from the PC same time and from the AEGO.

Without having to select source, or switch sources. If I want to listen to them "independently", I just make sure to turn off the other 2 devices of the 3.

I understand may need to get something ? Or is as simple as buying some connectors/adaptors only ?

If I have to get an equipment, I hope it won't blow me wallet (you can figure it out from my spending under USD150 on a pair of speakers).

I am not an audiophile by such a desired setup. But I hope I can get some advice here, please.

Thank you very very much for even reading this post.
