My current settings / setup for SPMC is listed out below:
  • Android: 5.1.1 HDMI image release 20160505 64gb version non-rooted
  • SPMC build: SPMC 16.3-0 Git:2016-04-30-22df3d0-dirty
  • CAT 6 cables between as many devices as possible: Pine64 and Fast Ethernet (100/10) Switch which is then connected to my router (not sure if this made a difference as I did not methodically test it, but before CAT 6 I had lesser cables between some of these devices and I know at that time SPMC was not working correctly either)
  • HDMI from Pine64 to Marantz Receiver
SPMC Options:
Videos:
     Playback:
         Adjust display refresh rate: On start / stop
         Sync playback to display: Off
     Acceleration:
         Allow hardware acceleration -MediaCodec

System:
     Audio output:
         Audio output device: Android, RAW Passthrough
         Number of channels: 7.1
         Output Configuration: Fixed
         Limit sampling rate (kHz): 48.0
         Stereo upmix: On
         Maintain original volume on downmix: On
         Resample quality: High
         Enable audio DSP processing: Off

Hopefully someone can build off of this and continue to improve the Pine64 media experience.

Hi,
I tried this setup with the last build (5.1.1 2016-10-19) and spmc 16.4.2 from the playstore. I don't have 5.1 surround. How did you do ? When i set "Output Configuration: Fixed", the passthrough option below is hidden. I only can set passthrough "on" with "Output Configuration: Optimized or Best match". When i set the passthrough option ON, i only get crashed sound. Did you tried that setup with updated software like mine since your post ?

I originally obtained SPMC via github, not the playstore.  When I have time later tonight I will try getting the latest build from github and see if I can make all the option changes that I could make in 16.3. I have not tried it with the latest android build for Pine64 (5.1.1 2016-10-19). I am still on android build 5.1.1 2016-07-11.
