RK3328-PC 是否支持HDMI音频输入
在Ubuntu20.04下,能看到 HDMI的音频输出设备:rockchiphdmiroot@firefly:/usr/local/bin# aplay -l**** List of PLAYBACK Hardware Devices ****card 0: rockchiprk3328 , device 0: ff010000.i2s-rk3328-hifi rk3328-hifi-0 []Subdevices: 1/1Subdevice #0: subdevice #0card 1: rockchiphdmi , device 0: ff000000.i2s-i2s-hifi i2s-hifi-0 []Subdevices: 1/1Subdevice #0: subdevice #0
看不到音频输入设备:

请问专家:
1)RK3328-PC能否增加在一个HDMI音频输入设备?
2)是否需要重新编译Linux内核?还是说在现有固件下配置alsa就可以实现?
只有音频输出,没有音频输入的。因为硬件上是不支持的。
