To have the input device detected like this:

..you need to enable the capture device in alsamixer. Click on F5 and choose ¨Capture¨. Then click on the spacebar.

When enabled the ¨--------" will change like this:

Thank you for your reply. Here is the snapshot from radxa 5B+

I can enable Headset Microphone as your explanation.

But, what i want to have is hdmi input device. Here is the same snapshot with orange pi 5+ with hdmi input device.

I compared the dts files for rock-5b and rock-5b-plus from these links. https://github.com/radxa/kernel/blob/linux-6.1-stan-rkr1/arch/arm64/boot/dts/rockchip/rk3588-rock-5b-plus.dts https://github.com/radxa/kernel/blob/linux-6.1-stan-rkr1/arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts https://github.com/armbian/linux-rockchip/blob/rk-6.1-rkr3/arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts https://github.com/Joshua-Riek/linux-rockchip/blob/noble/arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts https://github.com/Joshua-Riek/linux-rockchip/blob/noble/arch/arm64/boot/dts/rockchip/rk3588-rock-5b-plus.dts no dts file for rock-5b-plus at armbian.

I don't know well about linux kernel, but i guess rock-5b-plus.dts file is the reason for no hdmi-in audio. Hope this search can fix this problem. Thanks.

I have the same problem ! No hdmi input audio in system

[vtv3000]

And I don't have analog audio input too

[jhcho-hanvision]

And I don't have analog audio input too

You can try your audio jack plugged.

[vtv3000]

Ok I will try to plugin audio jack

But hdmi cable was plug in and no audio . In alsamixer I can see hdmi input but not have control . Gstreamer cannot have sound from hdmi

May be need EDDID file ?

I encountered this issue too, the problem was that the overlay configuration was using the DUMMY codec. I have fixed that and compiled a tdbo that you can place in your overlays directory and reference in your u-boot config (see Joshuas documentation).

enjoy hdmi-in audio actually having sound
