any loudspeaker needs an amp to emit sound, any digital media needs to be converted by a DAC before playing through a loudspeaker.

therefore yes, but it's 95% likely the amp is built into your speakers and the DAC is built into your motherboard's sound card. it's almost certain those are good enough for you.
