how to connect audio cable to pc

Here are the common methods to connect an audio cable to a PC:
Using a 3.5mm Audio Cable:
Prepare the cable: Make sure you have a 3.5mm audio cable. The two ends of the cable are usually 3.5mm plugs.
Locate the audio – out port: On a desktop PC, the audio – out port is typically on the back of the CPU box. On a laptop, it is generally on the left or right side of the keyboard. This port is usually green and marked with a headphone symbol.
Connect the cable: Insert one end of the 3.5mm audio cable into the audio – out port of the PC and the other end into the audio – in port of the audio device (such as speakers or headphones).
Using a USB Cable:
Check the audio device: Ensure that your audio device has a USB interface and is designed to connect to a PC via USB.

Find a USB port: Locate an available USB port on your PC. There are usually multiple USB ports on the front and back of a desktop PC and on the sides of a laptop.
Connect the device: Plug the USB cable of the audio device into the USB port of the PC. The device will usually be automatically recognized and installed with drivers. If not, you may need to install the drivers manually according to the device instructions.
Using an RCA Cable with Adapter:
Prepare the cable and adapter: You need an RCA cable and a suitable adapter, such as a 3.5mm to RCA adapter. The RCA cable has red and white connectors, which represent the right – channel and left – channel audio signals, respectively.
Connect the adapter: Insert the 3.5mm end of the adapter into the audio – out port of the PC.
Connect the RCA cable: Connect the red and white RCA connectors of the cable to the corresponding ports on the adapter, and then connect the other end of the RCA cable to the audio – in port of the audio device. Usually, the audio – in port of the device will be marked with red and white colors to indicate the right – channel and left – channel inputs.
Using an HDMI Cable:
Check the device: Make sure that your PC and audio – visual device (such as a TV or soundbar) both have HDMI ports and support audio transmission via HDMI.
Connect the HDMI cable: Insert one end of the HDMI cable into the HDMI port of the PC and the other end into the HDMI port of the audio – visual device.
Set the audio output: On the PC, set the audio output device to the corresponding HDMI – connected device in the sound settings.
