After contacting the i2S DAC PRO (IQAUDIO) manufacturers helped me finally find a solution to this issue. The DAC is now recognized and I can play music with it. The solution was to use Raspbian.

Re: No driver for Pi DAC PRO for Pi 3

I contacted the Pi DAC PRO hat manufacturers. They insisted they only support Raspbian, and did not give me details of what files are necessary to make their product work. I installed Raspbian as instructed. Including the lines: dtoverlay=iqaudio-dacplus and dtparam=i2c=on,i2s=on,spi=on in /boot/con...

Re: No driver for Pi DAC PRO for Pi 3

First of all sorry for the delay. I have been busy building and testing a custom amplifier. That is the good news. The bad news is I am still unable to use my Pi DAC PRO.

Using locate to search for the necessary kernel modules I found they actually are installed but for some weird reason they are not loaded. The files are in the directory: /lib/modules/4.16.14-v8+/kernel/sound/soc Seeing they are installed I tried to use modprobe kernel-module to load them but failed...

No driver for Pi DAC PRO for Pi 3

Last September I purchased a Raspberry Pi 3B+ and an i2S DAC PRO hat. I am posting here because I cannot find a driver for this sound card. What I find are ready made installation images that I do not want. The reason for this unwillingness to use a ready made image, is because I want to set up my P...
