In the PS3 settings, go to audio settings and choose "automatic". This procedure does not really change any settings, but in my case, it fixed my problem (my 875 had not received bitstream audio from the PS3 slim either).
It might be that some corrupted settings get written over when you go into that PS3 menu and choose "automatic".
Also, make sure your TV is receiving an HD signal. If the TV input is receiving standard definition (480 or 576 lines) then you need to change the video resolution in the PS3. Personally, I had wanted the PS3 to "force" 1080p so in the video settings menu, I left the 720p and 1080i boxes unchecked. This resulted in a 1080i Blu-ray being output as 480p. Hence, the audio was not high resolution either (HDMI audio and video bandwidth are shared).
