[Orin NX]audio codec RT5640 with rel36.4.3

Hi Nvidia,

I ref this [ref] to setup audio codec RT5640 on my Orin NX custom board.

Every function was OK, but under the ubuntu GUI when I tested speaker function like below picture ,I observed
the Input Device will also be action.

This is my amixer setting:
amixer_setting.txt (4.1 KB)

So my question is does there an error in my amixer path setting?

Diff with the JP6.0 used amixer setting:
amixer_setting.txt (2.7 KB)
the different was amixer -c APE cset name="CVB-RT Stereo DAC MIXL DAC L1 Switch" on and
amixer -c APE cset name="CVB-RT Stereo DAC MIXR DAC R1 Switch" on Maybe this the main cause of this phenomenon?

Many Thanks!!
