  41          If you don't have a sound card in your computer, you can include a
  42          driver for the PC speaker which allows it to act like a primitive
  43          sound card.
  44          This driver also replaces the pcspkr driver for beeps.
  45
  46          You can compile this as a module which will be called snd-pcsp.
  47
  48          WARNING: if you already have a soundcard, enabling this
  49          driver may lead to a problem. Namely, it may get loaded
  50          before the other sound driver of yours, making the
  51          pc-speaker a default sound device. Which is likely not
  52          what you want. To make this driver play nicely with other
  53          sound driver, you can add this into your /etc/modprobe.conf:
  54          options snd-pcsp index=2
  55
  56          You don't need this driver if you only want your pc-speaker to beep.
  57          You don't need this driver if you have a tablet piezo beeper
  58          in your PC instead of the real speaker.
  59
  60          Say N if you have a sound card.
  61          Say M if you don't.
  62          Say Y only if you really know what you do.
