sound card sounds a semitone to high

[sistaskriket]

Hello,
I noticed this when using a music-editing-program. I found that every note was replayed a semitone to high, "C" sounds C-sharp, "D" sounds D-sharp etc.

I also compared my two computers playing a tune on Youtube simultaniously.
the faulty computer played the melody at a higher pith than the other computer.
The sound card is a Realtech Audio HD. The .computer is a ASUS, Windows XP

This problem has emerged recently. Apparently some change has been made to the soundcard, I am unaware of how and when.

I'm most greatful för any suggestions how to solve this.

Best regards
Hartmut Blau

Try updating and/or reinstalling your drivers.

Definitely driver related.

Faulty drivers.

Make sure "A" is set to 220Hz if you have any such option. And reinstall drivers.

What`s the program? Is this the case for any other application? If it`s not, I`d point to the app, not the drivers.
