very likely, because your soundcard has a chipset, that provides these.
To save costs, many different soundcards are build with the same
chipset, high-price, pro-cards have DA/AD-converters for all digital
channels of the chipset (and thus analogue in/outs for all channels)
cheaper cards with the same chip come with only 2 or 5 converters for
the digital ports on the chipset.

Classy DA/AD-converters are expensive, you can make great recordings
with a card with 2 decent converters and crappy noise with another card
that connects the same chipset to cheapo-converters.
