Is Auto Switch to HDMI Audio Possible?

Question

I have a dv5-1235dx laptop and use vista, and finally figured out how to get the hdmi sound to work after searching this board and other sites (by manually choosing hdmi as default playback device), but it appears this requires a manual switch every time the hdmi cable is plugged in.  Have updated all drivers etc. (intel high definition hdmi), but still requires manual switch when I want to watch something on my hdtv.  Is there any other driver or solution that would just switch over to hdmi audio automatically when plugged in?  Seems like this is a common issue, and one that ought to be fairly easy to resolve, but i'm  not really that tech savvy so maybe it's more complicated and just an HP/intel issue that can't be resolved?  Anybody have any workarounds for this?

First of all, its not a Intel/HP issue and your playback device will automatically be set to speakers once you disconnect your HDMI cable.and be automatically set to HDMI once you connect your HDMI cable to the laptop.
Its similar to how you connect your headphone to headphone jack on the laptop. Make sure setting - HDMI as default playback device has been done when you have disconnected your HDMI cable from the laptop and not when its connected to the laptop.
In order to do,
Go to Control Panel\Hardware and Sound and click on sound . On playback tab, right click on white (blank) area and you would see 2 options (Show disabled Devices and Show Disconnected Devices). Make sure both options are checked to have all playback devices listed. 
Now right click on HDMI ouput device option and ensure "Set as default device" option is checked to hear audio from external display while playing picture on external display.
