Not aware of that - AFAIK LPCM stands for Linear Pulse Code Modulation - and is used to differentiate from other forms of PCM encoding (DPCM - Differential PCM, Log - Logarithmic PCM etc. - though these are seldom/never? used in mainstream audio applications in the HTPC realm) - I've never taken it to mean multichannel PCM. I've always assumed PCM is a short-hand for LPCM (as all mainstream PCM audio is based around Linear PCM sampling/encoding?) - with Multichannel PCM or Multichannel LPCM referring to the non-stereo variants. (Personally I use 5.1/7.1 PCM usually to be explicit)
