Das ist kein Fehler, sondern so gedacht. Das steht ja auch in der Doku:
Zitat:
Eventually because of the lack of hardware to communicate with, support for Beep was dropped in Windows Vista and Windows XP 64-Bit Edition.
In Windows 7, Beep was rewritten to pass the beep to the default sound device for the session. This is normally the sound card, except when run under Terminal Services, in which case the beep is rendered on the client.
Bei mir piept auch die Soundkarte, also alles wie es sein soll.
