Help A/V Issue: How do I output audio to a different source when using HDMI?

[justttsayin]

Okay here's my issue: I have a dock for my Samsung Galaxy Tab, and this dock has a AUX output and a mini-HDMI output. Is there anyway to get the video to output through the mini-HDMI and the audio to output through the AUX? Both the audio and the video default to output through mini-HDMI, but I was wondering if there was a way around that?

I would seriously doubt that would be possible.
