Hello!
OK, great. I don’t see anything to suggest that the codec is not detected. Furthermore, I see that you do see it listed under …
$ sudo cat /sys/kernel/debug/asoc/codecs
This means that the codec has been probed successfully by the kernel and in other words it is detected.
In your DT you have …
nvidia,xbar = <&tegra_axbar>;
rt565x_dai_link: nvidia,dai-link-1 {
link-name = "ti-capture";
cpu-dai = <&tegra_i2s1>;
codec-dai = <&aic32x4>;
cpu-dai-name = "I2S1";
codec-dai-name = "tlv320aic32x4-hifi";
format = "i2s";
bitclock-slave;
frame-slave;
bitclock-noninversion;
frame-noninversion;
bit-format = "s16_le";
bclk_ratio = <0>;
srate = <48000>;
num-channel = <2>;
ignore_suspend;
name-prefix = "z";
status = "okay";
};
nvidia,dai-link-2 {
link-name = "aic32x4-codec";
cpu-dai = <&tegra_i2s1>;
codec-dai = <&aic32x4>;
cpu-dai-name = "I2S1";
codec-dai-name = "aic32x4";
format = "i2s";
bitclock-master;
frame-master;
format = "dsp_a";
fsync-width = <0>;
bit-format = "s16_le";
name-prefix = "x";
status = "okay";
};
You should only have 1 link for the codec and not 2. So you should remove one of these.
Next you need to ensure you have the ‘nvidia,audio-routing’ DT node set up as Igal has in this post for the codec.
Did you modify the codec driver as Igal has?
Have you tried using his play.sh and record.sh scripts?
