Can anyone tell me how to access the "white screen" menu properly on a QIP7100 P2. My dynamic audio setting is not working with HDMI cable. I would like to try changing the audio out to L-PCM. For one there is no menu key on this set top box front. Two when i get the menu to pop up using the remote I do not see any audio settings only video settings, and no "other HDMI" settings. I did a search here but i only found info on other boxes not the 7100 P2
