Steve: SoundSource should work just fine.

JackW: All of our apps feature built-in version checking, which is on by default. This runs every 14 days. If you want to check more frequently, you can always choose Check for Update from the application's main menu.

Damnathan, Daveylee: Thanks for the support.

Cespur: Be sure to grab Airfoil 4.5.1, which addresses that issue.

Jonathan: Airfoil? No, we're at Airfoil 4 now.

Chris: It's unlikely to be a bug, but it could be some tricky settings. Contact us directly for support if it happens on Lion, once Instant On is updated.
