I have a RPI5 and Codec Zero that don't seem to be working together. I have cruise many other posts about this and none of the solutions have helped me. My Codec Zero is from PiShop and is a black one which I understand to be the original IQAudio units if that matters. I ran through the official tutorial (https://www.raspberrypi.com/documentati ... audio.html) to try get this to work with no success.
When changing the /boot/firmware/config.txt file, I have tried both and and neither worked.
I have tried uncommenting dtparam=i2c_arm=on, dtparam=i2s=on, and dtparam=spi=on in my config.txt file, as I thought that possibly there was a communication issue. That didn't help.
When I put the hat on the RPI, the green LED is on. What is odd thing is that when I run $ grep -a . /proc/device-tree/hat/* I getThis tells me the RPI can at least talk to the Codec Zero. However, when I try running $ aplay -l all I get is This suggests that the RPI doesn't recognize the Codec Zero as an audio device. I've also tried adding the -D IQaudIO-Codec when issuing (mentioned here: viewtopic.php?p=2126205&hilit=codec+zero#p2126205)
I don't know if it matters but when I create the file .asoundrc in my home folder, it doesn't exist after a reboot.
I'm hoping this can be resolved. Please help if you can. I am at a complete loss.
