Most people today use laptops instead of desktops,
and most "onboard" (attached to the motherboard) laptop sound cards are substandard. They don't have
high enough output, and they usually can't produce the lower tones.
Desktop sound devices aren't much better. They
fail the same tests, but usually not as poorly as laptop devices.
You will have the option to order your Shakti System with a USB sound
device that has the highest output possible, with excellent "low-frequency response".
