Missing audio driver?

#1

the distro is armbian that I downloaded from https://github.com/radxa-build/rockpi-4b/releases/tag/20220601-0955

aplay -l and pacmd list-sinks show only the hdmi audio device.

how can I get the audio play through 3.5mm jack

我用的github上radxa-build里面的armbian
aplay -l 和pacmd list-sinks 都只显示hdmi声卡
我怎么才能从3.5mm接口放出声音

Hi - did you ever resolve this problem ?

I am having the same problem with DietPi

recently I fixed audio problem in armbian. can you try newer armbian kernel?

you have a problem (device is recognized, but no output) with recent kernel, right?

Actually I fixed the first part of the problem ( that the internal analog sound was not being detected ). this was resolved by upgrading kernel from 5.15.76 to 5.15.80.

So now - the hardware, ie internal audio (not hdmi audio) is detected - and selected. And alsa mixer seems to work - and mpd is running… BUT - still no sound from attached speakers. If you have any tips or advice to make it play sound - they would be greatly appreciate…
