S905X - LPCM (AAC) 5.1 issue (LPCM 7.1 works fine)
I recently upgraded three S905X boxes and all of them have a strange issue where LPCM 5.1 is not working, but LPCM 7.1 is. This has worked fine until I upgraded to 19 Matrix. It might be related to an earlier reported issue: 19.0-Matrix Discussion - #97 by raytestrak
Samples from Kodi.wiki at Samples - Official Kodi Wiki
LPCM 5.1 (no sound)
LPCM 7.1 (sound)
Output from /sys/devices/virtual/amhdmitx/amhdmitx0/config shows that for LPCM 5.1, the audio config is not changing from default. Meaning that it’s not able to recognise 5.1, but 7.1 A strange case indeed.
LPCM 5.1
audio source: SPDIF
audio type: L-PCM
audio channel num: 2 channels

Cheers and thanks for the incredible work you guys have done! Looking forward to Amlogic-ne when I switch to S905X4 in some months
