+          If you don't have a sound card in your computer, you can include a
+          driver for the PC speaker which allows it to act like a primitive
+          sound card.
+          This driver also replaces the pcspkr driver for beeps.
+
+          You can compile this as a module which will be called snd-pcsp.
+
+          You don't need this driver if you only want your pc-speaker to beep.
+          You don't need this driver if you have a tablet piezo beeper
+          in your PC instead of the real speaker.
+
+          It should not hurt to say Y or M here in all other cases.
