I have a quirky problem with audio playback through my laptop. it currently has a Nvidia GT330 and it's connected via HDMI to my pioneer SC1222 receiver which then connects to my panasonic P55ST50. Sometimes I like to just play music from my laptop, such as mp3's or pandora etc. however, I dont want to leave the TV on as i don't want to burn in images/ want to conserve power. as soon as i power off the TV, the audio stops and then starts playing through my laptop. is there some type of setting I on my laptop that will keep outputting digital audio through the HDMI into the receiver?
I'm also soon to be replacing this with a new HTPC w/ intel HD 4000 graphics but am anticipating a similar problem when i power off the TV.
