A Profile 1.1 or 2.0 player can send the mix as PCM, and optionally may also transcode and bitstream or convert the PCM mix to analogue, depending on the hardware capabilities, codec and user options (fig. 5 of the Dolby whitepaper).

The Panasonic BD30 can send PCM if you select PCM output, but 7.1 is reduced to 5.1 only via HDMI and 2.0 via S/PDIF. It can also bitstream DD 5.1 (via HDMI and S/PDIF) if you select "bitstream" option and decode to analogue 5.1. Since it cannot internally decode the lossless codecs, it will only decode the companion DD or core DTS in the primary track.

Bear in mind the secondary audio stream on BD-ROM is limited to 256 kbps, 48kHz and 5.1-channels.
