Check the Faders in your soundcard's software mixer, accessed either via the little speaker icon in the taskbar or via the Control Panel.

See if any of them have mysteriously been turned all the way down or muted.

If no joy there, check the control panel for whatever DXi synth you may be using, locate its Volume Fader tab and check to see that all volume faders including the Master are still turned up ALL THE WAY.

Don't know if this is your exact problem, but I have encountered that occasionally on an XP SP3 machine here. Problem is that it happens so sporadically that I don't think it is easy for development to duplicate, or to duplicate at all. Might be some mundane difference in an OS setting somewhere or the like.

I do seem to notice that happens only after I've done a lot of editing or the like in BiaB, leading me to believe that it is some sort of resource issue maybe.

And - If all else fails, try a "Return to Factory Settings" under the Opt menu, but pick the SECOND button there, so that the wizard can re-address your soundcard and MIDI synth.


HTH,
