I need to mute/un-mute the sound card at startup and shutdown.
I have found some code to do the work, but often Windows slams through the shutdown and the sound never gets muted.
Can someone please tell me how to pause the shutdown long enough for my app to mute the sound? I can use a simple TTimer to pause the app long enough for it to run the muting and then let Windows get on with shutting down.
How do I tell Windows to wait though?
I notice that if I leave Firefox running and try to shutdown, Windows stops with a message, "These programs are preventing windows closing..." and needs a click to force Firefox to close. I need to find that.
