Any use for a sound card these days?

In the past Ive always brought dedicated sound cards for my computers, however these days most motherboards have some sort of audio support built in, in fact many even are capable of surround sound, and a large amount of the audio processing can be done completely in software anyway (eg as I understand, XAudio2, which is set to replace DirectSound does all processing in software, just using the hardware to actually send the final audio data to the speakers).

So considering those things is there actually any point to fitting a dedicated sound card in modern computers?

EDIT: So does the improved quality of dedicated audio hardware apply to software based audio solutions which seem to be becoming more popular?

Solution 1:

The motherboard integrated soundcards usually have much more noise, noticeable at higher gains, due to proximity to other components and not being shielded. This noise can be very unpleasant, and if you have good speakers/headphones, it's even more noticeable.

If you care about the sound quality and/if you have good quality speakers/headphones, you should get a good soundcard, perhaps an external one if you plan on recording something aswell (easier to connect, no interference).

On another note: did anyone ever notice in some computers you can hear a static noise when moving the mouse with max volume?

EDIT: If you really want to see how your soundcard performs comparing to others in the market, download the audio benchmarking tool at audio.rightmark.org and compare your results with some commercial and professional sound cards out there in their site. You'll probably need a cable to connecto the speaker and microphone jacks. (though I think this might be a little bit too much if you're not into audiophile/professional stuff)

Solution 2:

I'm using the motherboard's sound in my HTPC, with optical output to my receiver; it does 7.1, DTS, AC3, and other three letter acronyms. I also game on the system, and have no noticeable performance impact from not having a "dedicated sound processor" or whatever the marketing folks are saying these days.

I find that sound perception is subjective, and there's more variables in the equation than many other system components. Various hardware can affect how something sounds, and not everyone can even tell there's differences. Some people (like me) cannot detect certain kinds of white noise or interference.

The speakers and/or headphones you use can have more impact on your sound experience than whether you use onboard sound or a standalone sound card. If you're hooked up to a receiver (like I am), that will affect sound output. Some receivers will do additional processing (for good or bad) on the signal they receive.

I didn't install a sound card in my system to save on money - I have a $500 receiver after all - I did so because its an additional component with another set of drivers, and possible area for conflict. The onboard sound chip provides what I need at no additional cost, and the quality is good enough for me.
