Sound out of computer speakers?

Disclosure: I'm using a Mac

Ok, now how do I get the live sound to come out of my computer's speakers? When I select "built in" as the output, nothing happens. The only other output option is the rig kontrol, but it would sound a lot better out of my 200w speakers than my 15w amp...

 

Ok, I'm NOT on a Mac, but if you're using the ASIO driver at least, you simply have to use the same device for both input and output. I.e. if you're connecting your guitar to RigKontrol, like I do, you must connect your powered speakers (or other amp system) to the RigKontrol output, or you'll get no sound.
On the Mac side you have other options than ASIO, which may be more flexible.

 

For playing through my computer speakers I'm using the RigKontrol output, going back to my soundcard; You just have to physically plug cables from your Rig Kontrol back to the soundcard input of your computer. Works fine, although the sound isn't remotely accurate as to GR's amp simulation; my small speakers and subwoofer color the sound a bit.

For a more realistically simulated sound you would send the signal to powered studio monitors; the difference is astounding!

 

Make an aggregate device with Rig Kontrol in and Built-in audio -- you'll be able to use both.

 

How do I do that?
