What are the advantages and disadvantages of sound card?

Answer 1

A dedicated sound card has the following advantages and disadvantages.

Most modern computer motherboards will have some kind of onboard audio chip which is sufficient for most gaming and audio listening. However some audiophiles may requires a higher degree of standards when it comes to their listening and may have equipment capable of detecting and noticing the shortcomings of a mass-produced, cheap, onboard sound chip.

A dedicated card will first have it's own chip which means it takes a load off the CPU when it comes to sound effects and input and output. This means the CPU could be freed up for more important tasks.

The inputs and outputs on a dedicated soundcard will usually be of a better craftsmanship then the ones on a motherboard and thus will have less analog interference. This is important on the back of a computer which is already brimming with EMI due to the myriad of devices in close quarters.

Usually a dedicated sound card will have a better DSP (digital signal processor) and will be capable of higher quality sound output and input. This means you can run a better quality of sound in and out of the card.

The disadvantages of course are price. A dedicated card can run as little as thirty dollars to as much as several thousand for high end models.

They also take up a precious expansion slot on a motherboard which could be used for other devices you might need.

Various manufacturers may have varying support for some programs and devices and hardware, always a concern. Onboard sound chips tend to be almost universal in their support, one advantage. A dedicated card might not openly support alternative operating systems such as Linux or BSD bases.

Hope this helps!
