Pi Zero - screen and i2s using same pins, no sound

[bulbisaur685]

Hello,
I am making a specific project for which I needed a Raspberry Pi Zero W and a small screen, as well as an i2s audio device. I am using RetroPie V4.7.1 on the system.
The screen is a high resolution 2.8" display by iUniker that I purchased from Amazon (https://www.amazon.com/Raspberry-iUniker-2-8-inch-Resolution-Touchscreen/dp/B07H8ZY89H/ref=sr_1_1?crid=23LPRNIHCX4LQ&dchild=1&keywords=iuniker+2.8&qid=1620921282&sprefix=coin+button%2Caps%2C270&sr=8-1)
And the i2s audio decoder is from Adafruit ([url]https://www.adafruit.com/product/3678[/url])
I have both devices connected to the pins on the Pi Zero, but when going into the settings for audio I am getting information that the audio is disabled. I have read that this may have something to do with the screen's touch input settings, which I am not using and would be fine with disabling so that there could be audio output via i2s.

I have messed with the codes in the /boot/config.txt file:

#added lines, likely for iUniker screen
gpio=18=op,dh
gpio=7-8=a2
dtparam=spi=on
dtoverlay=ads7846,penirq=27,swapxy=1,xmin=200,xmax=3850,ymin=200,ymax=3850
display_rotate=3
dtoverlay=mzdpi
framebuffer_width=640
framebuffer_height=480
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=0x07f003
hdmi_timings=480 0 41 20 60 640 0 5 10 10 0 0 0 60 0 32000000 1
#adafruit audio lines below
dtoverlay=hifiberry-dac
dtoverlay=i2s-mmap
#my added lines trying to get audio to work
dtoverlay=pwm-2chan,pin=18,func=2,pin2=19,func2=2
gpio=18-19=a5
gpio=21=a0

I have also read that enabling this next section is supposed to work, but it black screens the entire system when its enabled and I try going into an emulator or audio settings:

# Enable audio (loads snd_bcm2835)
#dtparam=audio=on

And I have tried uncommenting

dtparam=i2s=on

but that seems to have no effect.

There are two .dts files added by the iUniker screen as well, the latter being ridiculously long:

The error that typically displays when I attempt to open an emulator or the audio settings is the following:

ALSA lib pcm_dmiz.c:1108:(snd_pcm_dmix_open) unable to open slave
lvl0:  AudioManager Error - Unable to open SDL audio: ALSA: Couldn't open audio device: No such file or directory

I've been struggling with this for about two weeks now and after exhausting Google and forum posts, I'm asking for help. Thanks in advance, let me know if there are any more details needed!

@bulbisaur685 said in Pi Zero - screen and i2s using same pins, no sound:

I have both devices connected to the pins on the Pi Zero, but when going into the settings for audio I am getting information that the audio is disabled

That message is shown because the audio configuration utility only knows about the on-board audio. For any other configuration - where you disabled the on-board - you'll need to configure the audio yourself.

My suggestion would be to start with the audio configuration first (in config.txt) and then try to configure the screen once you've got audio working.
