Exporting LPCM AUDIO FROM NLE Premier Pro FOR MASTERING BD disk at 5.1 LPCM

General question with Premier pro. I Finalized my TFA Edit master in which I used converted the DTS 7.1 HD track to LPCM 5.1, which I then muxed into a M2TS container to premier pro can edit it. Issue is now, I rendered my video, but I want to render my audio mix to LPCM or at least WAV64 so I can mux it together with TSMUXER. Issue is I am having issues with finding an export option that keeps my audio Lossless and something that TSmuxer can read (audio)- I have the newer version of Premier pro CC and it has great export options to DD 5.1, but this will create a 2 generation audio quality hit.

Anyone have any idea’s?

Try exporting WAV/W64 from PPRO, use some utility to split that up into individual wavs, load that in DTS MAS to encode DTS-HD MA.
