Hi, nvidia
I am currently adapting the ES8316 codec to AGX Thor. However, I have encountered some issues.
The clock frequency of AUD_MCLK is 49.15 MHz. However, when I play music, there is no sound output.
cat /proc/asound/cards
0 [HDA ]: tegra-hda - NVIDIA Jetson Thor AGX HDA
NVIDIA Jetson Thor AGX HDA at 0x88090b8000 irq 270
1 [APE ]: tegra-ape - NVIDIA Jetson Thor AGX APE
NVIDIA-CESAGXThorJAT_001-NotSpecified-Jetson
The dts nodes I added are as follows:
i2s@92b0000 {
status = "okay";
ports {
port@1 {
endpoint {
dai-format = "i2s";
remote-endpoint = <&es8316_ep>;
//bitclock-master;
//frame-master;
};
};
};
es8316_codec: es8316@10 {
status = "okay";
#sound-dai-cells = <0>;
compatible = "everest,es8316";
reg = <0x10>;
clocks = <&bpmp TEGRA264_CLK_AUD_MCLK>;
clock-names = "mclk";
sound-name-prefix = "ES";
port {
es8316_ep: endpoint {
link-name = "es8316-playback";
remote-endpoint = <&i2s4_dap>;
mclk-fs = <256>;
};
};
};
sound {
status = "okay";

And I didn’t find the virtual sound card I was looking for in the “sound → Output” section.
Thanks.
Best Wishes.
