snd-pcsp: adjust help texts to frighten users
Added the warning text to the help of snd-pcsp about the possible problem with this driver so that user can know of the problem in advance. Also, removed the obsoleted text about ancient pc-speaker patch in CONFIG_SOUND help. Signed-off-by: Stas Sergeev <> Signed-off-by: Takashi Iwai <>

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.
