Audio support for 3.5mm jack on librecomputer S905D3/A311D boards

[deepanchal]

I found this thread on audio issues https://hub.libre.computer/t/alta-aml-a311d-cc-audio-issues-dummy-output-and-no-sound/3488/19
and after running these commands, I got audio to work but only on hdmi. Audio isn't working for 3.5mm jack

# FRDDR A to TDMOUT C
amixer sset 'FRDDR_A SINK 1 SEL' 'OUT 2'
amixer sset 'FRDDR_A SRC 1 EN' on
amixer sset 'TDMOUT_C SRC SEL' 'IN 0'

# TDM C to TOHDMITX
amixer sset 'TOHDMITX I2S SRC' 'I2S C'
amixer sset 'TOHDMITX' on

# FRDDR B to TDMOUT B
amixer sset 'FRDDR_B SINK 1 SEL' 'OUT 1'
amixer sset 'FRDDR_B SRC 1 EN' on
amixer sset 'TDMOUT_B SRC SEL' 'IN 1'

# TDMOUT B to ACODEC
amixer sset 'TOACODEC SRC' 'I2S B'
amixer sset 'TOACODEC OUT EN' on
amixer sset 'ACODEC' 90%

Any ideas on how to get audio working for 3.5mm jack as well? Thanks
