So I attempted to configure the latest Raspbian for my hifiberry dac pro.
I used the documentation here:
It appears to be a bit out of date:
/etc/modprobe.d/raspi-blacklist.conf - this file no longer seems to exist.
This line does not exist either in /etc/modules.
I foolishly made a simple mistake and actually *added* the lines:
blacklist i2c-bcm2708 blacklist snd-soc-pcm512x blacklist snd-soc-wm8804
To a blacklist file, and I commented out the line in /boot/config.txt which related to the Pi's built in audio hardware (instead of commenting the non-existent line in /etc/modules).
I followed the rest of the documentation and after a reboot I could see hifiberry modules in lsmod output.
However, aplay -l displayed no audio hardware!
When I realized my mistake I deleted the blacklist file from /etc/modules.d and rebooted. My Pi failed to come up!
I'm going to check around when I get home - but the main reason for my post is to suggest that the documentation no longer seems to fit new versions of Raspian.
