PCM multichannel (LPCM) in X96 Air

Help & Support Hardware
9

I tried 7.1, still only 2 channels work :(. My settings are as follows

  1. Audio output device: ALSA:AML-AUGESOUND, HDMI Multi Ch PCM
  2. Number of channels: 7.1 (tried 5.1 too)
  3. Output configuration: Best match (tried optimized and fixed too)
  4. Stereo upmix: off
  5. Allow passthrough: off

Thanks for the help, but seems like something is off. May be X96 Air is different from ODroid C4. I will see if I can find a thread specifically for X96 air and ask someone with the same box if they were able to get LPCM working.
