How to connect radio to PC in order to let computer's speaker replace the radio's speaker ?

Get a 3.5 mm male to male cable. Connect one end to the radio speaker output. Connect the other end to the computer microphone or input.

If your computer doesn't have a mic port, get a usb 3.5 mm stereo adapter

It would be easier to connect the PC speakers directly to the radio. Then you don't need to keep the PC and an application like soundrecorder or similar running while you want to listen to the radio.

Or get a PC radio card that you install directly in the PC or as a USB deivce.

Besides that, most radio stations these days stream their content on the internet, so you probably don't even need the radio.

Thank you all for your fast reply. As the radio is very good, I would like to listen to the radio through my PC. I tried connect the radio to the PC(mic port) through male to male cable, but it cannot work. Maybe i did something wrong ?

It depends on what type of output ports your radio has and what type of input ports your PC has. One scenario has already been specified by NVIT — 3.5mm male-to-male:


Another scenario is RCA jacks on the radio to 3.5mm on the PC:


On the input side, you may have a Line-In (blue below) or Mic-In (pink below):


Both are 3.5mm.

Another possibility is that your radio and/or PC could have optical ports:


There may be other possibilities, but those are off the top of my heard. Regards, Joe

As I mentioned, connect the speakers directly to the radio. If your PC only has internal speakers and not external ones, then they will be too crappy anyway as they will be too small to output good quality sound, and those of your radio will probably be better.

If you really need to connect the radio to the PC, then you will have to run an application that loops the signal from the line in port of your audio card (to which you have connected the radio), through the sound card and to it's output. You will also have to adjust the settings of your application so it does what you want. If I'm not mistaken, it should be possible via the soundrecorder of windows, Better of course is audacity.

These PC are laptop. I am using 3.5mm male-to-male, it cannot work. I am trying this thing in another laptop, but the laptop does not have port for microphone. Which device do I need to buy to connect the 3.5mm male to male cable ? USB adapter ?

I think rindi might be right. It is not just physical connection, and it needs to have a lot parameter configured.

Don't use the mic port.  Use the line-in port.  This is the blue port.  See Joe Winograd's picture above.

You may also have to check the computer's settings for the sound ports to see that Line-in has been enabled and to adjust the volume settings for Line-in as well.

I've used them and they do work.

TOSHIBA L645 laptop, it does not have Line-in port. There are only two 3.5 port, one is for mic and another is for headset

A great device

two laptops

I don't understand. Which one (make and model) do you want to plug the radio into — and what ports does it have?

To Joe,  "I don't understand. Which one (make and model) do you want to plug the radio into — and what ports does it have?"

I was trying to plug into TOSHIBA. Since it was unsuccessful, I doubt there is a problem in the first PC, then I tried second laptop, but I found the second laptop does not have port for mic

i have never seen problems with that, since the laptop input impedance is much higher
