[Invalid] - Odroid C2 SPDIF sound output

[Simon42]

Hi ,

 

i buiild a SPDIF connector like shown here:

https://forum.odroid.com/viewtopic.php?t=21477

 

it uses the J7 SPDIF output which is connected to HDMI.

On coreelec i can clearly see a HDMI soundcard output with aplay -L , i dont see that on armbian....

 

Is odroid c2 spdif output on armbian working ? why do i not see this soundcard that f.e. libreelec is showing ( i have 2 odroid c2s , one is running coreelec in my living room with HDMI connector working)

 

im using a little older armbian distro since the latest has ethernet issues on C2 (im using 20.11 , kernel 5.9.10 debian edition )

 

regards,

Simon

Good morning, I have a very similar topic and I think it is related to the ALT function assigned to pin 2 on header J7 of Odroid C2.

I ran a script taken from here https://wiki.odroid.com/odroid-c2/application_note/gpio/gpio_default_check_program and got

ALT4 as result with HK ubuntu 20 while I get ALT2 with armbian 23.11, which is "I2S_IN_01" instead of "SPDIF_OUT" according to S905 datasheet found on the Hardkernel site.

I have the same connector described in the link https://forum.odroid.com/viewtopic.php?t=21477, but it is impossible to get digital audio output with armbian.

I have checked other posts but was unable to find any solution. Can you please help me?

Thank you.
