[DllImport("kernel32.dll")]
public static extern bool Beep(int frequency, int duration);

Unhelpful related to your question, but there's also the Console.Beep[^] method (so you won't have to mess with native methods). And on another note, the PC speaker won't beep on 64bit systems apparently. And here's why[^]

even Console.beep isnt helping

Based on your stated criteria, I suggest the following API method.

[DllImport("user32", CharSet=CharSet.Unicode)]
internal static extern int MessageBeep(int uType);

with uType = 0xFFFFFFFF -- A simple beep. If the sound card is not available, the sound is generated using the speaker.

but what if there are no speakers?
It should generate sound from system
