I have a rPi 2 an a hifiberry-dacplus and the hifiberry-digi.
If I install one of these board and apply the driver setting from your site (https://www.hifiberry.com/guides/configuring-linux-3-18-x/) Raspbian wont start properly (when booting to the GUI). The panel bar (bar in the top of the screen) will appear-disappear-appear-disappear... and raspbian wont start properly. The cards themselve do work, they are visible in aplay -l, and I can play a sound using mplayer.
The problem appears to be in the removal of "snd_bcm2835" from /etc/modules
When I remove this line Raspbian wont start properly.
When booting I do notice the following lines:
"snd-rpi-hifiberry-dacplus sound: ASoC: CPU DAI (null) not registered"
"snd-rpi-hifiberry-dacplus sound: snd_soc_register_card() failed: -517"
From some information that I found is that you claim I2C is not working properly, but when I connect a logic analyser to the system I see valid data on both I2C interfaces (the one to the DAC and the one to the EEPROM).
How can I fix my raspbian with the hifiberry cards, because if I cannot boot to the GUI with these cards installed they are worthless to me.
No panel in raspbian when hifi berry installed
