For me, I have to add -c 0 to run these command:

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

# TDM C to TOHDMITX
amixer sset -c 0 'TOHDMITX I2S SRC' 'I2S C'
amixer sset -c 0 'TOHDMITX' on

# FRDDR B to TDMOUT B
amixer sset -c 0 'FRDDR_B SINK 1 SEL' 'OUT 1'
amixer sset -c 0 'FRDDR_B SRC 1 EN' on
amixer sset -c 0 'TDMOUT_B SRC SEL' 'IN 1'

# TDMOUT B to ACODEC
amixer sset -c 0 'TOACODEC SRC' 'I2S B'
amixer sset -c 0 'TOACODEC OUT EN' on
amixer sset -c 0 'ACODEC' 90%```

We will implement Alsa UCM2 profiles for Alta and Solitude in the coming image update.

This Alsa UCM2 profiles will be implemented on images or firmwares?
I thought if it can be applied for firmware, that would help more, regardless the distros.

UCM2 profiles are in userspace.
