RT5640 does not work on AGX Orin

[tom.lin]

hi
I use custom carrier board on AGX ORIN + 36.4.3, The music is not output to the speaker. When measuring i2c, i2s1_dout continues to output clock, but p3737-a05 only outputs when playing. What adjustment is missing for this to happen?

We refer to the discussion below. The problem is still the same, card1 in cards does not grow out, and CVB-RT does not grow out either.

[AGX ORIN]audio codec RT5640 is not working with rel36.4

Hello, teams. I use custom carrier board, AGX ORIN rel36.4. I have a similar issue with the link below. I’m using ABKO’s SP1 speaker model for audio testing in GUI. In rel35.5.0, I didn’t modify any DT files related to audio codecs. It worked well and the sound came out of the speaker. However, In rel36.4, I also didn’t modify any DT files related to the audio codec, but the speaker doesn’t make any sound. I only deleted the PD controller code from the “tegra234-p3737-0000+p3701-0000.dts”…

From DT logs, it seems the “nv-public/overlay/tegra234-p3737-0000+p3701-0000-dynamic.dts” overlay is not applied on boot.
