Audiogram 6 Headphones

Usually when you plug in headphones, the speakers turn off. Not so with Audiogram 6. I want to record a track then play it back through the headphones while I record another track in sync, but if I turn down the speaker volume, the headphone volume also goes down. Other than unpluging the speakers (rather unprofessional), is there a way to only play back through the headphones?
Thanks for any help I can get.

Had this problem and I ended up getting help from a Yamaha Tech dude.  He Emailed me a different USB driver and when I power up Cubase you cam switch to the Yamaha USB Driver, after that all the computer sound is routed through the phones output on the Audiogram.  Its super, cause you you get a monitor signal and your playback.  Are you on Mac or PC? 

I am on PC with XP Pro. I just got an email from Yamaha tech support who said that the playback sound is routed through both the stereo out (to the speakers) and the Phones output, so if I want to hear the first track - let’s say an instrumental track - on the headphones while recording a separate vocal track, and don’t want the mic to pick up the instrumental playing through the speakers, I have to unplug the speakers or turn them off at the speakers (I don’t have on/off or volume controls on my speakers). It seems a little mickey mouseish that they don’t have a separate volume for the phones and speakers.

It all has to do with the way Cubase interacts with different audio drivers. I am using Vista but with the Yamaha USB driver you will be able to hear the instrumental track through the headphone out on the Audiogram rather than the computers phone out, then when you want to use the speakers as a monitor simply switch the audio driver.  Would that work?

I’m using the yamaha driver. I have speakers plugged into the Audiogram 6 and headphones plugged into the Audiogram6. I’m not using the other speakers that are plugged into the computer ports, nor the headphones plugged into the computer.
I’m meaning that the speakers plugged into the Audiogram and the headphones plugged into the audiogram both sound at the same time, and are controlled by the same volume control knob on the audiogram. If I turn down the volume on the speakers so that the first track isn’t picked up by the mic while recording the second track, the headphone volume also turns down. They are in parallel. So, I have to unplug the speakers from the Audiogram so I can hear the first track through the headphones (also plugged into the Audiogram) while recording the second track.

How’s it going Rob?  Ever get things working?
