first things first, my setup.
- Olevia 237V LCD HDTV (1080i) connected to PS3 via HDMI cable only (no other audio cables from ps3 to tv)
- standard run of the mill Sony 5.1/DTS AV receiver connected to PS3 via Digital Optical Cable
- PS3 set to output all formats to Digital Optical (aac,dts,dolby,pcm). Movie/BD audio set to Bitstream.
what i've found out, atleast in my case, is that its the order in which i turn on my devices and how i turn off my ps3.
whenever i power off my PS3 when watching a movie (just have movie playing, hold PS button, turn off system) and then if i turn on my setup in this order i get both HDMI and Digital Optical sound on my PS3.
- PS3
- TV
- Receiver
it almost seems like by doing this tricks the PS3 in its digital/drm rules of audio output.
i have now duplicated this 5 times in a row.. however, i do have to do the exact steps above to get it to work including power down the ps3 while in a movie/dvd.
also, this works ONLY with DVD movies, not Blu-ray movies
my youtube clip of it in action!
