That capability most often is used for older HDMI-capable AVRs which don't have enough CPU power to be able to both decode the high-bitrate lossless audio tracks and apply room equalization algorithms at the same time. i.e. for the conversion of high-bitrate multichannel lossless Dolby and DTS tracks to high-bitrate multichannel lossless LPCM in the player.
However, my AVR can decode Dolby Digital & DTS (just not the other formats) and that's why I chose bitstream. If I set them to Bitstream and I select BD-Video Secondary Audio to "off", I don't get any sound
]Some AVRs can't handle the high bitrates used for the "core" (lossy) Dolby and DTS signals on Blu-ray discs. I fear this might be the case with your AVR. At least, that would explain why bitstreamed audio is silent for you.
if I leave the Secondary Audio to "on" I get sound. I was just wondering that even though I'm getting sound, if that's really the best setting.
When Secondary Audio is enabled, the player can only output PCM, which is limited to two-channel stereo over the SPDIF coax and optical digital connections. The bitrate used for stereo PCM is the same as is used for CDs (or at most only slightly higher), so that explains why you can hear the results when you enable "mixing".
Many BDs include standard DD5.1 audio tracks, too, although they're usually soundtracks dubbed with different languages. You might try selecting one of them as a test when you enable bitstreaming without Secondary Audio.
I don't normally listen to those tracks, so I don't know what bitrates they use. If you could provide a (short!) list of BDs you'd like to try this with, I could take a look this evening (about 8 hours from now) to see if I have any of them. My Sony player can display the bitrates of the audio and video tracks and thus I could determine if they're low enough that you should be able to hear them.
I thought that was for the analog outputs only.
Sorry, yes. I thought you wanted to try that as an alternative to the digital connection. (i.e. hook up the L/C/R analog outputs of the player to the L/C/R inputs of the multichannel analog input set on your AVR.)
Configuring your AVR's speaker settings with surrounds and LFE disabled will cause it to downmix incoming 5.1 digital audio to your 3.0 speakers. (Presumably you've already done this.) Also, if you turn on Dolby ProLogic in your AVR, it should expand two-channel stereo (either digital or analog) to use the center speaker. With ProLogic disabled, I believe that two-channel stereo tracks should cause only your Left and Right speakers to be active, and not the Center.
At some point you might want to consider replacing your AVR with one that supports HDMI. That'd eliminate these annoyances, although it'll introduce you to some others
