OK, I've created a clean build, and there is no difference:

Without hifiberry.conf:

Code:

rpi512:~ # lsmod | sort
Module                  Size  Used by
regmap_mmio             1921  1 snd_soc_bcm2708_i2s
snd_soc_bcm2708_i2s     5202  0
snd_soc_wm8731          9498  0
snd_soc_wm8804          6854  0

rpi512:~ # aplay -l
aplay: device_list:268: no soundcards found...

With hifiberry.conf:

Code:

rpi512:~ # cat .config/modules-load.d/hifiberry.conf
#snd_soc_bcm2708
snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_pcm5102a
snd_soc_hifiberry_dac

rpi512:~ # lsmod | sort
