Sound on Tinkerboard S, help needed

[ChrisO]

Hi

Could anyone assist me in getting sound output on my Tinkerboard S?
product: Rockchip RK3288 Asus Tinker Board S
v26.2.1 for Tinker Board running Armbian Linux 6.18.35-current-rockchip

$ aplay /usr/share/sounds/alsa/Noise.wav
Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

No output on the connected earphones.
I don't know where to start to debug the problem.
Any aideas anyone?

Thanks
Chris

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

armbianmonitor output's here:

So it it this one: https://tinker-board.asus.com/series/tinker-board-s.html

 

In the log I see 'USB Audio', also HDMI audio and there is a 3.5mm jack. I am not sure what audio and what the goal is. HDMI audio on Rockchips can be tricky, I have seen simulator kernel problem messages, depends also on which bootloader.

 

Then I am not sure if on-board eMMC plays a role or not. The SD-card mmc0 is properly initialized but there is also mmc1 and mmc2

Can you post output of

sudo lsblk

 

And if eMMC is there, there might be old U-Boot there.

 

Further there is quite some repeated registerdumps, that is not a good sign, but don't really understand why that happens.

My bad, it's the first ever TB, without S

And this one has no eMMC.

Hello, normally audio on Asus Tinkerboard works out of the box.

 

I have not tested HDMI audio for a long time because I don't have a suitable monitor. It should work, but I can't bet on it. Analog audio also should work.

 

You need to set the correct device to aplay because the default may be set to HDMI (or SPDIF).

 

The command aplay -L will give you the various ALSA outputs you can play on, find something like plughw:CARD=analog,DEV=0 and then use -D aplay flag to specify the device. You should get something similar to this:

 

aplay -D plughw:CARD=analog,DEV=0 my-audio-file.wav

Thank you jock!

After some trial and error

 

aplay -D hw:CARD=OnBoard,DEV=2  sound.wav

 

works.

 

Now I have to imagine how to play the sound via bluetooth...
