hi
i have X920 and don't have sound on RSA,
on HDMI - OK

@valbor
Did you enable the device in /boot/config.txt?

Hi
I haven't understood a question
I did nothing yet, on LibreElec there is no sound on a RSA too
PCM5122 is in the I2C-mode: 17 pin - Low, 18 pin - High
pinout:
PCM5122 name Rpi name
11 SDA 3 SDA1
12 SCL 5 SCL1
23 LRCK 35 GPIO19
21 BCK 12 GPIO18
22 DIN 40 GPIO21
16,20,24 - GND
19 - NC

If you mean the 'root' account:
Code:
sudo su -RE: Adding an I2S DAC for audiophile quality sound. - Skywatch - 9th May, 2018 06:48 PM
What version of pi are you using?
Are you sure that the board will work the the version of pi you have attached it to?
What is the output of cat /etc/asound.conf ?
To edit the config file you simply need to use 'sudo nano /boot/config.txt' - Then when changes done use ctrl-o to save and ctrl-x to exit and reboot the pi.

I use WinSCP

You do not need admin (root) pw
Put card into your card reader, plug reader into usb port of your (Windows)-PC and edit config.txt file on first partition on sd-card (this VFAT partition, so you do not have any problems from Windows side)
append lines to config.txt described in "For RuneAudio" section in the link you posted in your first post

Sure, if card is not enabled, no drivers loaded no soundcard is available
Plz read section "For RuneAudio" of the article you posted and add the two lines

PuTTy - help me

Well done - I hope that put a smile on your face when it worked.
BTH it is easier now with DT entries than it was before with wheezy - but still you have to get it right, which you did!
