Some things you've written don't make sense to me.
When you've come to this forum for help, first present the symptoms of the "default" system, not one with hand-edited changes to deep system parameters such as gpu_mem. It may seem innocuous but ....
I used the HiFiBerry-equivalent board, which also has the 5122 DAC chip, for more than a year without any clicks/glitches. Nothing found in an Internet search should be accepted at face value. I thought these settings were in the board driver and/or board itself.
No /boot/config.txt? That's very odd. I don't expect it and can't repro it by playing with alsamixer.
I don't understand what you mean. There's no auto-detection of i2S devices in either 64-bit or 32-bit moOde.
This seems backwards. I'd expect first to select a specific i2S type/driver and then after reboot see the output device has been set to "i2S audio device".
Good luck in your hunt.
