請問如果電腦唔買音效卡，係咪冇聲？如果有耳機，冇音效卡，有聲？

音效卡是內建於主板上，如果沒有壞就一定有聲，音效卡需要裝上驅動程式才能有聲，如果你自裝windows就檢查一下

音效卡有內建和外接兩種 你買主機板一般都會隨機都附上內建音效卡

1. In the past, yes. Nowadays, no.


In the past, sound card is a standalone item that must be purchased with any computers.


However, nowadays, practically all motherboards, including OEM motherboards, come with sound chipset that eliminates the need of a standalone sound card.


If you can find any connectors for sound on a motherboard, then the motherboard has equipment all necessary sound components. Hence, no standalone sound card is needed.


2. No. At the minimum, you have no place to plug that in.
