Hi, all:
I attempted to port RT5616 to Orin Nano and modified the following files:
tegra234-soc-i2c.dtsi.txt (8.5 KB)
tegra234-p3767-common-audio.dtsi.log (7.9 KB)
tegra234-soc-audio.dtsi.log (27.6 KB)
rt5616.c.log (41.1 KB)

But there is currently no sound output, the following is the debugging information：
dmesg.log (66.4 KB)

We are using i2S2, but there seems to be an issue with the DPAM path for i2S2 here.
I have executed the following command before, do I need to execute anything else?

amixer -c2 cset name=“I2S2 Mux” “ADMAIF2”
amixer -c2 cset name=‘DAC MIXL INF1 Switch’ 1
amixer -c2 cset name=‘DAC MIXR INF1 Switch’ 1
amixer -c2 cset name=‘Stereo DAC MIXL DAC L1 Switch’ 1
amixer -c2 cset name=‘Stereo DAC MIXR DAC R1 Switch’ 1
amixer -c2 cset name=‘HPO MIX DAC1 Switch’ 1
amixer -c2 cset name=‘HP Playback Volume’ 39

Sorry for the late response.
Is this still an issue to support? Any result can be shared?
