I have been trying for the last month to get a HAT I've designed that contains a TI TLV320AIC3110 audio code chip to be recognized at boot or even by using modprobe to load the driver. I can't get ALSA to see the chip. This is on a RPi5
I have really tried to search online for solutions, but nothing seem to work.
I am using UBUNTU 24.04 Server, as I need ubuntu-frame and wpe-mir-kiosk for my dedicated IoT with no HDMI connections. This setup doesn't offer vcdbg and I can't seem to get ANY debug info.
Just to add that I can see the device with as 0x18 and can send commands to it
I will post my .dts file here if anybody can point me to what's wrong.
Any help would be appreciated. I can supply the schematics of the PCB also
