有内核参考吗？声卡出来了就是一直播放失败，不知道哪里少改还是什么

使用的linux6.1.54版本内核，移植论坛大佬提供的驱动。
目前现象是驱动加载后引脚上能有1.5V电压，声卡也能正常的显示出来。
内核启动时有以下输出：
[ 1.191964] ALSA device list:
[ 1.195021] #0: Loopback 1
[ 1.197913] #1: suniv Audio Codec然后使用speaker-test播放时喇叭只有一个上电的吧嗒声。
在DMA和声卡驱动中加上日志输出，从日志看DMA和声卡都有正常工作。
按理speaker-test播放应该会输出噪音，不知道有没有哪位大佬知道什么情况？
附播放时DMA驱动和声卡驱动日志：

#22 Re: 全志 SOC » f1c200s使用主线uboot，spi速度很慢的解决方法记录 » 2023-04-28 18:19:40
使用sunxi-fel直接把uboot，kernel，rootfs烧录到内存中启动方法：
1.修改uboot配置
bootargs=“console=ttyS0,115200 earlyprink panic=5 rootwait root=/dev/ram0 rdinit=/linuxrc rw”
bootcommand=“bootz 0x80008000 0x80d00000 0x80c00000”
2.生成uImage格式的rootfs
cd /opt/buildroot-2018.08.2/output/target
find . | cpio -o -Hnewc |gzip -9 > ../rootfs.cpio.gz
mkimage -A arm -T ramdisk -C none -n uInitrd -d ../rootfs.cpio.gz /var/www/html/rootfs.cpio.gz.uImage
3.烧录文件
sudo ./sunxi-fel -p uboot ./u-boot-sunxi-with-spl.bin write 0x80c00000 ./suniv-f1c100s-licheepi-nano.dtb write 0x80008000 ./zImage write 0x80d00000 ./rootfs.cpio.gz.uImage
