Frequently asked questions
Do internal sound cards improve audio quality over onboard?
Yes, generally they do. They have better DACs and dedicated power circuitry, which reduces interference and improves clarity. For professionals, the difference is noticeable in low-level details.
Can I use an internal sound card with a laptop?
No, internal sound cards are designed for desktop computers. For laptops, consider an external USB DAC or sound card.
Are there any internal sound cards with XLR inputs?
Some cards, like the Creative Sound Blaster AE-9, include an external module with XLR and 1/4-inch inputs for microphones. Others may have a 3.5mm mic input only.
What is the difference between 5.1 and 7.1 sound cards?
5.1 supports up to 6 channels, while 7.1 supports up to 8. If you have a 7.1 speaker system, a 7.1 card allows full surround sound. For headphones, virtual surround can be processed regardless.
Do I need a sound card for music production?
For basic production, onboard audio may suffice, but for critical mixing and recording, a dedicated sound card with low latency and high SNR is beneficial. Some producers prefer external interfaces, but internal cards offer low latency.
How do I install an internal sound card?
Turn off your PC, open the case, and insert the card into an available PCIe slot. Secure it with a screw. If required, connect the power cable. Then install the drivers. It is simpler than most think.
Are there any sound cards that support DSD or high-res audio?
Yes, many modern cards support high-resolution audio up to 24-bit/192kHz. Some even support DSD playback. Check specifications for these features if needed.
Will a sound card reduce CPU usage?
Yes, because the sound card processes audio independently, it can offload work from the CPU, especially for gaming and effects. This can improve system performance slightly.
Can I use multiple sound cards at once?
Yes, you can install multiple sound cards in separate slots. You can assign different applications to each via the OS. This can be useful for having multiple audio outputs simultaneously.
What is the best sound card for Linux?
Many sound cards work with Linux, but some need community drivers. Cards with C-Media chipsets often have better support. For professional use, consider a card with a proven track record, like the ASUS Xonar series.
Our take
If you prioritize sound quality and don’t mind the price, the ASUS Essence STX II is the clear choice for professional audio. If you also game and want a versatile card, the Creative Sound Blaster AE-9 wins with its all-in-one design. For most others, the EVGA Nu Audio Card provides excellent value without sacrifices.
