Thanks. I'm afraid I have more or less tried all of those (if I understand them correctly). Like I said, I can get sound from the computer, so the speakers work and the volume is turned up. I also tried the headphone, but to no avail. I think the problem may be with the soundcard, as when I test that seperately, it gives no sound. I tried downloading a realtek driver for it, but that had no effect, other than that the device is now called realtek rather than something generic.
In the sound output screen I have for options:
-Hauptwerk VST link
-DirectSound: Realtek Digital Output (Realtek High Definition Audio)
-DirectSound: Primary Sound Control
-DirectSound: Speakers (Realtek High Definition Audio)
The last two are approximate translations from Dutch.
My fear is that either I do not have the correct driver for the soudcard (and I have not been able to find which I should use based on the souncard ID), or that the souncard is simply broken. The strange thing is that all the while my computer still does produce sound, so even if the soundcard is the problem, it should not be insurmountable.
I just want to play....
