i2s audio with pcm5102
-
Has anyone tried it and succeded? I did everything according to the latest manual, connected BCLK, LCLK and DIN, but got no sound.

you need to update (oupgrade command) to late firmwares and activate (command line) i2s mode for the gpio . you need to use the 3 mentioned pins that are specific on the onion boards . there is a 2 bulletarticle tutorial.

tell us your progress and trials.

Yes, I performed all steps. I can the the card listed, no errors when I play internet radio, but no sound from the headphones
-
@Denis-Mikhalsky Have you changed the GPIO muxing to enable I2S?
omega2-ctrl gpiomux set i2s i2s
-
@Lazar-Demin of course, I did. I assume otherwise I would had errors when trying to play internet radio.
Is Build177 OK? Shall I oupgrade to the absolutely latest build?

@Denis-Mikhalsky
I use b177 I get some correct sound (not perfect due to some incompatibilities with my standart dac) but that should work b177 is not the problem look else for the cause .I think I got an idea for you to check later : pcm 5102 has a format pin for hardware configuring to adapt to the received i2s mode format. maybe you could change from one to another between LJustified and i2s justified but I do not think that is the problem of lack of sound (only proper decoding of bits without overdrive/distortions).

@sonus I've made some progress. On my module, it's needed to connect XMT (HW Mute) to 3.3V AND to connect FMT to Gnd.
The only remaininng issue I have is that i2s pin assgnemnt is not persistent. I have to type omega2-ctrl gpiomux set i2s i2s after every reboot.

@Denis-Mikhalsky
also you need to configure your pcm5102 to i2s mode format (not LJ) on a first trial . it should work perfectly.
