Systemlautsprecher funktioniert nicht

Hallo Steffen,

ich habe den Ton über den normalen Lautsprecher bekommen. Den Mainboard-Pieper habe ich nicht benutzt…

MSDN sagt zu Beep() folgendes:

Zitat:A long time ago, all PC computers shared a common 8254 programable interval timer chip for the generation of primitive sounds. The Beep function was written specifically to emit a beep on that piece of hardware.
…
Since then, sound cards have become standard equipment on almost all PC computers. As sound cards became more common, manufacturers began to remove the old timer chip from computers. The chips were also excluded from the design of server computers. The result is that Beep did not work on all computers without the chip. This was okay because most developers had moved on to calling the MessageBeep function that uses whatever is the default sound device instead of the 8254 chip.

Schlußfolgerung:
Wenn dein Mainboard keinen 8254-Chip mehr hat, wirst du dort auch keinen Ton per Beep() bekommen. Hast du schon mal die in der MSDN-Hilfe erwähnte Funktion MessageBeep() benutzt?
