An idea…
This is something I’d like to see - but never have.
A Sound-Card-Firewall.
Basically, like Zonealarm allows you to give applications permission (or deny them) to access the network/internet - how about a piece of software that allows you to give applications permission to access the soundcard… So I can have sound off for web-browsers, but on for, say the email notification sound from Outlook - preventing annoying flash ad’s for smilies from suddenly shouting something through my speakers when I’m online.
