[XavierNX][RT5640]Auido playback exit immediately

Hi charles.huang,

Mixer settings seem incomplete. Please refer The audio ALC5640 can't work on I2S0 and I2C2 for Xaiver NX - #15 by lcc0610 and use right mixer controls.

Also ensure pinmux for DAP3 is set appropriately as per link below

Jeston NX + audio Codec RT5640 cant work

Hello! The first thing that you need to check is that the pinmux for the I2S pins are configured correctly. Are you using the Jetson Xavier NX devkit or the Jetson Xavier NX module with another board? You can check the pinmux by executing the following … $ sudo grep dap3 /sys/kernel/debug/tegra_pinctrl_reg Bank: 0 Reg: 0x02431048 Val: 0x00000440 -> dap3_fs_pt4 Bank: 0 Reg: 0x02431050 Val: 0x00000450 -> dap3_din_pt3 Bank: 0 Reg: 0x02431058 Val: 0x00000400 -> dap3_dout_pt2 Bank: 0 Reg: 0x024310…

Thanks,
Sharad
