Jeff,

Is it possible in the non-general case?  I know that or example on my mbp it seems like this might be possible, since when the headphones are plugged in and I reboot I hear the reboot chime through the external speakers.

Thanks for the response!

Generally, this isn't possible. On most of our hardware, the headphones and the speaker are driven from the same device and are mutually exclusive.

I keep getting requests to have PTHVolume (http://pth.com/products/pthvolume) support the ability to switch the Audio Output to built in speakers even if a headphone is connected.  I know the hardware technically supports this but is this something that can be controlled via CoreAudio or is it locked up in the Kernel Driver and thus practically inaccessible?
