Good. Just so you understand what's going on, when Secondary Audio is ON, and a Secondary Audio track is available anywhere on the disc you are playing, the Blu-ray specs require the player to act as if you are using a Secondary Audio feature on the disc, even though you aren't. That's tied up in how BD-Java programming on the disc can initiate things like Secondary Audio without giving the player prior warning. Secondary Audio is usually found as menu sound effects or as commentary track audio for some picture-in-picture commentaries.
Now, Secondary Audio can't be mixed into the Primary audio track while that's still a Bitstream. So when Secondary Audio is engaged, the Bitstream Primary track first has to be decoded into LPCM in the player. Then, if you've set Bitstream output, the result after mixing has to be RE-encoded back into a Bitstream for output. But no consumer device has the horsepower to re-encode a lossless Bitstream on the fly like this. So a lossy Bitstream format is used instead. In the case of the 103, what's used for the re-encode is the highest bit-rate form of DD or DTS -- at 5.1 channels -- according to whether the original Bitstream was Dolby TrueHD or DTS-HD MA.
The upshot is that while using HDMI Audio Bitstream, you should leave Secondary Audio OFF unless you actually want to use a feature on disc requiring it.
Note that if you use Analog audio output, or use HDMI Audio LPCM, you can leave Secondary Audio ON all the time without any such potential loss of quality to the Primary track when there's no actual Secondary Audio mixing happening. The full quality of the Primary track -- including channel count, sample rate and bit size per sample -- is preserved. (While Secondary Audio is actually present and selected, the Primary track is usually attenuated as part of the disc's audio mixing programming.) This is one reason why I suggest people use HDMI Audio LPCM.
When you bring up the on-screen info display, the audio format being read off disc is shown in the lower left. That's preceded by an icon. The overlapping discs icon indicates Secondary Audio processing is NOT engaged. The wavy line icon indicates Secondary Audio processing IS engaged -- again, whether or not you've actually selected to use a Secondary Audio feature on the disc.
If you press Page Up/Down to change what's shown on the on-screen Info display, the bottom line will now show what's going out on the HDMI outputs.
