I believe Himedia Q5/Q10 can decode HD audio & pass as PCM (RAW or PCM options are in their Android settings; also native LPCM 5.1/7.1 already pass fine). But, adding to noggin's reply, go RPi2 instead since you want multi-channel PCM, which is fine for 90% usage/users out there. However, some matrixed metadata in THD & DTSMA tracks get lost w/player doing the decoding (vs. AVR), and you also lose ATMOS & DTS:X.
Possibly I should clarify why this is important.
In the long term I probably will invest in a decent audio processor, one that supports Atmos and DTS:X; but with all the new formats buzzing around I'm not sure the market is quite settled enough to spend a lot of money on that just yet. (Some years ago I shelled out several thousand on a Bryston SP1.7 which sounded great compared to its rivals at the time, but became essentially obsolete when DTS-MA and Dolby True-HD came along).
So, for the moment, I'm using my Oppo 105D blu-ray player as a sound source. It sounds very good, and it has HDMI inputs so you can use it as an audio processor for external sources. But it has two weaknesses. The first is that, while it can itself function as a media player for just about every other type of file, it can't stream MVC 3D - it can play a .mkv file containing MVC, but only as 2D, and it can't handle .iso images.
My first idea to get round this was to acquire a Mede8er MED600X3D. This isn't a Kodi device, of course, but it does a pretty good job of playing back MVC stuff in video terms; but there's a slight problem with the audio. The Mede8er can pass through any audio track as bitstream, and this works fine for plain DD or DTS; but the Oppo is unable to handle DTS-MA or Dolby True-HD on its HDMI inputs. (It handles them fine when it's doing its own streaming or playing a disk, but not when it's coming from an external device).
The Oppo HDMI inputs can apparently support multi-channel PCM input - either 6x192kHz or 8x96kHz. The Mede8er has an option to output "multi-channel LPCM", and I was hoping setting it to that would make it decode the movie sound track and output the result as 5.1 or 7.1 PCM; but apparently the only time this actually works properly is if the original video soundtrack is already in multi-PCM format - for DTS, etc. the PCM output is downmixed to stereo.
So, the fact that a media player can output multi-channel PCM is not in any way a guarantee that it can
decode DTS-MA and output the result as multi-channel PCM.
If the Q5 definitely can decode DTS-MA, then it might well do me as a substitute for the Mede8er; but I'd like to be sure about its capabilities before investing in one.
The Raspberry Pi 2 is an interesting option, but I'm worried by the comment at the start of the thread about it dropping frames and having problems with high bitrates.
