Does this mean that in addition to outputting Dolby True-HD on the HDMI, the player will create a lower resolution surround signal from the core soundtrack in HD and output it on the optical output?

With the appropriate settings (bitstream or raw or similar), the BD player will output DD5.1 or DTS5.1 on the optical cable, even if the BD itself has no such track (the HD audio is downconverted).

The SAP setting is really only for HD audio and needs to be turned off to listen to HD audio via HDMI.

1. I think that's OK, but if you hear no sound, then you may need to select the DD5.1 or DTS track as applicable/available. There's often an "audio" button which allows you to cycle through the various tracks by repeatedly pressing that button.

2. I don't see that this would improve things, but if you don't accept this setting, it may downconvert to PCM 2 channel? All of these players have many different settings and the operating manual is often useless.
