What the AI looks for in External Sound Cards
- Use case: interface vs DAC/amp
- XLR/instrument inputs plus phantom power for recording; headphone amp and DAC for listening and gaming These are different product types that share the 'sound card' label.
- Headphone drive
- Check output power against your headphone impedance and sensitivity; high-impedance cans need a stronger amp An underpowered output sounds quiet and thin.
- Microphone input
- Confirm a 3.5mm mic or combo TRRS input if you use a headset mic Many DAC/amps are playback-only.
- Platform compatibility
- Verify USB audio class support for consoles, Mac or Linux if you need them Some features require Windows-only software.
- Connection
- Bus-powered USB is fine for headsets; desktop amps for demanding headphones often use external power Power affects how much headroom the amp has.

Questions
Will an external sound card fix buzzing from my PC?
Often, if the noise comes from onboard audio. A ground loop to powered speakers needs an isolator instead.
