AIO3399J HDIM-IN 声卡设备如何发现
在原有SDK的基础上,做如下的调整:1)SDK版本:rk3399_linux_release_v2.5.1_20210301
2)按帖子:《rk3399j使用最新源码编译hdmi_in的固件》(https://dev.t-firefly.com/forum.php?mod=viewthread&tid=103343&highlight=HDMI-IN%2B%C9%F9%BF%A8)做更新。
3)按帖子:《AIO3399J 无法加载adbd》(https://dev.t-firefly.com/forum.php?mod=viewthread&tid=128070&page=1#pid312037)做更新。
4)采用官网提供的文件系统:Ubuntu20.04-Minimal_RK3399PRO_v2.20-12_20230203.img
重新build切刷新固件后:
1)可以通过adb-otg连接设备。
2)通过arecord -l, 看不到可录制的HDMI-IN声卡设备。
请问:是否需要更换文件系统?或者还需要做其他的什么修改才能在ubuntu下发现可录制的HDMI-IN声卡?

把开机的dmesg信息加在附件里了。 二周没人理了,是不是信息不够全,再补充一些:
