The Analog output and input devices are showing in the settings menu as shown below but I am not getting audio playback on my headphones.

Also, I see the error “sgtl5000 7-000a: ASoC: error at soc_component_read_no_lock on sgtl5000.7-000a: -5” and other similar errors in dmesg log.

Below is the dmesg log, other log and “kernel_tegra194-p2888-0008-p2822-0000.dtsi” which contains response of below commands.
sudo cat /sys/kernel/debug/asoc/components
cat /proc/asound/cards
pacmd list-sinks
pacmd list-sources
sudo cat /sys/kernel/debug/regmap/7-000a/registers

Have you checked the Audio Setup and Development — NVIDIA Jetson Linux Developer Guide 1 documentation to see if can help?
