As a suggestion there seems to be an overlay for the ILI9341 - perhaps it would be a good idea to link to it on this guide ?

There’s already an ILI9341 overlay. However, ILI9341 displays vary in how they are connected so you have to modify one of the existing overlays.

I2S is needed. Please supply more information.

  • I2S - please request if needed
  • PCM - please request if needed
  • SPDIF - please request if needed

I need I2S working though the signals are not in the 40-pin header. Currenly, aplay -L only shows CARD=LIBRETECH-CC.
lsmod shows: dw_hdmi45056 2 meson_dw_hdmi,dw_hdmi_i2s_audio
ldto shows no i2s.
uname -a shows Linux raspberrypi 6.1.23-04871-gb31bbd9b633c #1 SMP PREEMPT_DYNAMIC Fri Apr 7 05:45:13 UTC 2023 aarch64 GNU/Linux

Thanks, Eric.

You need to select I2S or PCM in alsamixer and then play some audio to test the output.
