使用以下命令查看声卡，可以看到目前有三个声卡

cat /proc/asound/cards

修改设备树

diff --git a/kernel/arch/arm64/boot/dts/rockchip/rk3399-jw-d039.dts b/kernel/arch/arm64/boot/dts/rockchip/rk3399-jw-d039.dtsindex 515334c127..5b592a852f 100755--- a/kernel/arch/arm64/boot/dts/rockchip/rk3399-jw-d039.dts+++ b/kernel/arch/arm64/boot/dts/rockchip/rk3399-jw-d039.dts@@ -118,6 +118,6 @@

修改过后，重新编译代码，烧录固件，再次查看声卡，只剩下一个声卡了
