DAC Lineout at pin #51,52 No sound

Hi everyone, I conncted my 3.5mm jack port L/R to pin #51 and #52, using aplay -Dhw:1,0 test.wav and there is only a start pulse, but no other sound at output.
How do you use the lineout ?

Does aplay -l show any devices?
If not, you will need a different distro.
Armbian official is still on Feb, and does not support audio
@igorp pointed me to this, which works fine for me (I used Armbian_23.5.1_Rockpi-s_bookworm_current_6.1.30.img.xz

Image you are using is already official stable build, just index on the download pages will be changed when mirrors sync is finished and release docs published, cca 48 hours.

Hi. Struggling with a similar issue. Using Armbian_23.5.2_Rockpi-s_bookworm_current_6.1.32 with the POE hat 3.5mm jack (analog 3.5mm the RCA cable). I see multiple output devices in alsamixer and aplay -l shows:
card 0: rockchiprk3308a [rockchip,rk3308-acodec], device 0: ff320000.i2s-rk3308-hifi ff560000.acodec-0 [ff320000.i2s-rk3308-hifi ff560000.acodec-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0

I am using the USB DAC whilst I troubleshoot getting the 3.5mm output working. Can anyone point me in the right direction to get this output working with alsa and squeezelite?

Many thanks in advance.
