EmuELEC in X96 air: 3.5mm headphone output

Recently, I install EmuELEC in the X96 air amlogic s905x3 4Gb version. Everything work fine except there is no way to output sound through 3.5mm audio jack. I already try to change some settings in alsamixer but no result. The android stock image has the 3.5mm audio jack output without any configuration.
It there any way to choose audio output? Thank you.

Here is some information about the system:

  • EmuELEC version 3.4
  • X96 air amlogic s905x3 4Gb ram
  • Have try all the setting EmuELEC provide in main menu. Audio output in system setting have only auto option. Audio devices in EMUELEC setting have more setting like (0,0),(0,1) but nothing work. Sound setting in image below.
  • play -L output:
null
    Discard all samples (playback) or generate zero samples (capture)

This is still on the CE to do list for the S905x3, so you cannot get it working as yet.

Thank you for your infomations. Just curious, can you show me where can i find the CE to do list you talking about? I can’t find it in github.

There is no official “to do list”, but this is a known problem that we are working on.
