Well sound card is not much necessary

Sound cards aren’t necessary. They’re more of an extra commodity.

Add-in PCI sound cards are becoming less common.

No, you don’t need to buy a sound card; you can either use the integrated audio processor on your motherboard with a variety of outputs, or the one on your graphics card that outputs over the DisplayPort/HDMI to your monitor.

If you have a somewhat elaborate setup that has a S/PDIF/TOSLINK audio-in, I’d probably recommend using an optical cable (no noise from other wires) to send your audio to an external receiver.
