Help text

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.

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 in a configuration file under /etc/modprobe.d/ directory: 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.

Say N if you have a sound card. Say M if you don't. Say Y only if you really know what you do.
