I'm trying to get my DAC+ board to work with my rPi 3 A+, which is running latest Raspbian. To do so, I've been following the instructions here.
One thing I noticed when following the instructions was that using "hifiberry-dacplus" in /boot/config.txt did not work (aplay reported no devices) whereas if I use "hifiberry-dac" then aplay -l reports:
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
Subdevice #0: subdevice #0
I'm not sure why that is, since the card has "DAC+" written on it.
Even so, if I plug headphones in and play a wav file, I hear nothing. Can anyone help me diagnose this?
