HDMI hijacks default playback device

[Reavance]

I have headphones through onboard audio set as the default playback device.

I have HDMI set to listen stereo mix (onboard) under recording devices so that I can get duplicate audio on my headphones and TV.

Windows 7 likes to set as HMDI audio as the default playback device when I am not looking (assumedly shortly after rebooting, but not quite sure when). And then I get no sound from my headphones because the programs are all playing on HDMI.

Is there way I can fix this?

Hmm; I think HDMI is mutually exclusive to pc { speakers & headphones }. If the HDMI senses a signal to the tv, then the others go off.

right-click on the speaker icon in the tray and view/set the playback devices
