how does USB a audio work on pc speakers if there is no usb port on my sound card of the same brand?

Answer 1

not sure what you are asking. i'm guessing you mean speakers that use USB cable for power and audio.

in that case, you should know that it doesn't plug in to your sound card. instead, it plugs in to your computer, which routes it to your sound card for processing.

Answer 2

The USB device acts as a "sound card" itself.

If you want to use the sound card in the PC, you need speakers that connect by 3.5mm audio cables, not USB.

With USB-connected speakers, the PC sound card is not required & the speakers connect to any suitable USB port on the PC.

Answer 3

use any USB port
