I have had two Raspberry Pi 2Bs for a while and just last week decided to get a HiFiBerry DAC and settled on the DAC2 Pro.
I have just gone through the process of installing it and have the following configured in /boot/config.txt.
dtoverlay=hifiberry-dacplus
However, when I go to set the audio output to be the DAC, it isn't available.
Looking at dmesg logs produces the following:
osmc@RPi2B:~$ dmesg | grep hifiberry
[ 8.379100] clk-hifiberry-dacpro clocks:dacpro_osc: Fail to register clock driver
[ 8.379155] clk-hifiberry-dacpro: probe of clocks:dacpro_osc failed with error -17
[ 8.624522] snd-rpi-hifiberry-dacplus soc:sound: ASoC: CPU DAI (null) not registered - will retry
[ 8.637792] snd-rpi-hifiberry-dacplus soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered - will retry
[ 9.301764] snd-rpi-hifiberry-dacplus soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered - will retry
I have tried on both Raspberry Pis as I read that there can sometimes be an issue with GPIO pins on Pis. But the same issue on both???
I really appreciate any help anyone can give me.
Thanks
