Activating of HifiBerry DAC without Web UI

Use the beta1, then activate the i2s driver. Then reboot. It works. Don’t update the firmware .

For the others, the problem on beta 1.1 resides on different naming of the i2s modules. You should be good to go by just editing /etc/modules

nano /etc/modules

and making it look like that

snd_soc_bcm2708 snd_soc_bcm2708_i2s bcm2708_dmaengine snd_soc_pcm5102a snd_soc_hifiberry_dac snd_soc_rpi_dac

Save with ctrl+x and reboot. Don’t enable i2s modules again!
