          You can compile this as a module which will be called snd-pcsp.
+          WARNING: if you already have a soundcard, enabling this
+          driver may lead to a problem. Namely, it may get loaded
+          before the other sound driver of yours, making the
+          pc-speaker a default sound device. Which is likely not
+          what you want. To make this driver play nicely with other
+          sound driver, you can add this into your /etc/modprobe.conf:
+          options snd-pcsp index=2
          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.
+          Say N if you have a sound card.
+          Say M if you don't.
+          Say Y only if you really know what you do.
