I’ve got my HiFIBerry DAC+ADC and I’ve been designing a new enclosure to make a guitar pedal. Here is my progress so far.
The Pi USB ports are pointing out the back. Power comes from a 9V pedal power supply and converted to 5V inside the box.
The left channel is used for the main guitar in and out. The right channel is used for the send/return jacks at the back of the enclosure. I’m hoping that the active buffer in the polytune will avoid any impedance issues with the direct guitar input.
There will be a stomp switch on the left for on/off, and one on the right for bypass. The pot in the middle modifies the output volume of the left channel.
I booted it for the first time yesterday and the output works fine, but the inputs are not showing up as alsa devices. My zynthian was running 4.14 kernel but I followed these HiFiBerry instructions to switch to their supported 4.18 kernel, but that didn’t seem to help
Is there anything I can do to get input working, or help out with the effort to add support for the HiFIBerry DAC+ADC?
Hello everybody,
im new to Zynthian…
RPi 3 with Standard Case. It works fine
But: I have buyed the HiFiBerry DAC+ ADC. No Problem with the DAC+ Driver. But i want to use the input and i followed the instructions by @steveb.
I have no luck: To much errors installing the new kernel.
Can somebody help me a little?
Thanks.
If you get an error message, please type it as it appears, “WRONG! Im an idiot!” is not a standard error and so isn’t much help to us.
btw: I hate Windows and MacOS, but if I need help from people who understand how to help me with them I tend not to go with it as a conversation opener. It’s an emotive subject though so I understand your hostility.
sudo su -
(you missed the critical hyphen at the end) is only needed to change to the root user, if you’re already root then you don’t need to run it.
If I remember correctly, I ended up running each line in update-kernel manually, omitting the sudo prefix in that script because I was already running as root.
Hello again,
if i say: >I hate Linux < it means ironic…
I am not an Linux Guru. If errormessages comes up i am at the end of my knowledge.
Last night i try it by hand to install the hifiberry drivers as @steveb suggest it…
I edit the /home/pi/zynthian-webconf/lib/audio_config_handler.py file and insert all the stuff
for the dac+adc card. audio_config_handler.py (9.9 KB)
It takes 2 hours before i understand that i must write “analogue” instead of “capture”…
But now it works and everything is fine for me.
Haha,
this is an fast’n’dirty “Remix” of the 808 Intro of Sexual Healing. Played from my phone directly
into the HiFiBerry input. Routed thru the MDA Delay with rough hand settings.
Its a pot to set the output level going to the amp. There will be a foot switch to the left which will be the on/off for the pi, and a foot switch on the right to be a full bypass.
The new SD image will include the new kernel supporting the Hifiberry DAC+ADC. I hope to release the new SD very soon!! Development is frozen now and the next SD image is my priority now…
Congratulations!
