Customizing raspberry to output audio

[sashgorokhov]

Hello! I am working on a little project that uses stratux raspebby pi image and some additional hardware (i2s audio amplifier and speaker) to make some sounds.

I am following i2s (not i2c!) amplifier instructions here (https://learn.adafruit.com/adafruit-max98357-i2s-class-d-mono-amp/raspberry-pi-usage) to get sound. The problem i have is that these instructions work with plain raspberry pi image but does not work with stratux image. Everythin is setup but there is no sound in stratux. Something is going on with stratux OS image and i hoped someone could give me a direction.

I am using US stratux image.

I tried:

• Used stratux config and enabled persistent logging.
• Disabling overlay using overlayctl disable.
• Updated /boot/config.txt and disabled everything fishy that stratux added (to check things)
• Ensured /etc/modules is correct
• Ensured /etc/modprobe.d/raspi-backlist.conf is correct

My only suspition is that my edits in /boot/config.txt are'nt beign respected because of overlay nonsense but i dont understand why, since i disabled it.
