moode audio with dac8x and camilladsp - ma00am - 11-17-2024

Hi!
I want to make moode audio work with a raspberry pi 5 and dac8x.
as i am a total noob on linux this is quite a challange Big Grin

when i run aplay -l
i get this result.

card 0: sndrpihifiberry [snd_rpi_hifiberry_dac8x], device 0: HifiBerry DAC8x HiFi pcm5102a-hifi-0 [HifiBerry DAC8x HiFi pcm5102a-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


Then i have tried to copy the example crossover to make a 2-way speaker (this is exactly what i cant to make, i just need to configure all the values later)

For some reason the playback channel section alters the number of channels from four to two.

I would ask in the main CamillaDSP thread at diyAudio.

People post their configs / questions and get lots of help :-)
