We are trying to test Jetson AGX Orin Dev kit audio ( It has devkit BSP only , not modified) , But it is not working as expected .
2 pin - GND of headphone
5 pin - headphone out left side
9 pin - headphone out right side.
In sound setting we made sure analog audio selection
Any configuration is required ?
Any input please…
Can you confirm if your Dev Kit has onboard audio codec?
Please dump following info on target:
$ i2cdetect -y -r 31e0000.i2c
Also please share output of following:
* cat /sys/kernel/debug/asoc/components * amixer -c APE controls
Above can help confirm if your board has onboard codec and its driver has been registered properly or not.

Hi Sameer PFA logs. Please check and suggest further.
Hi Sameer, Any update on this ?
Thanks for your logs
Perform below steps based on your environment.
On Host :
- Take backup of base DTB file.
- cd Linux_for_Tegra/kernel/dtb
- cp <file.dtb> <file.dtb>.bac
- Apply overlay and generate modified DTB
$ fdtoverlay -i <file.dtb> -o <file.dtb> tegra234-p3737-audio-codec-rt5640 .dtbo
For example: file.dtb => tegra234-p3701-xxxx-p3737-xxxx.dtb , use right dtb base file by referring the flash log.
Let us know if you still face issue in playback.
Hi @mkumard ,
Step1: I am getting no such file or directory. Logs attached with ls command response. (Step1_AudioExlore1)
hmecd001409@DSC:~/BSP/Osbourne_orin/Linux_for_Tegra/kernel/dtb$ cp tegra234-p3701-0004-p3737-0000.dtb tegra234-p3701-0004-p3737-0000.dtb.bac
hmecd001409@DSC:~/BSP/Osbourne_orin/Linux_for_Tegra/kernel/dtb$ fdtoverlay -i tegra234-p3701-0004-p3737-0000.dtb -o tegra234-p3701-0004-p3737-0000.dtb tegra234-p3737-audio-codec-rt5640.dtbo
Couldn’t open blob from ‘tegra234-p3737-audio-codec-rt5640.dtbo’: No such file or directory
Failed to read ‘tegra234-p3737-audio-codec-rt5640.dtbo’
Steps2: For 2nd steps to apply patches, not able to find “tegra234-p3737-overlay.dts” files. Downloaded from “Log in | NVIDIA Developer” But it came with dtb file.
Please can you share more info or file ?

Are you able to apply above patch?. If so it should enable codec on your board version. Can you give a try with build and flash.
Overlay patch did not apply. Only With enable_onboard_codec.diff patch able to enable audio and now audio coming.
Thanks lot Mkumard. :-)
Welcome!. Also please note in the next Jetpack release the audio codec will be enabled by default.
