Hello all,
I just discovered Pisound and Modep last night and am EXTREMELY excited to get into it. I was just about to order a Pi 4 when I saw they just released news of the Pi 5. Curious to see if the Pisound hat will be compatible with Pi 5 and if not, what peoples plans are for a work around. Cheers!

Welcome to the Blokas community!
Just my $.02. Get a Pi4 with 8 GB of memory. It may be challenging to get a Pi5 at the moment and the Pi4 will handle Modep just fine.
Chances are, Pisound will work with Raspberry Pi 5 as well, it should be backwards compatible with existing hardware, we’ve ordered some RPi 5 boards and we’ll verify compatibility once received.

Can’t wait to hear the results. Thankyou!
I tried it, and i got this message (maybe some Problem with 64bit?!):

Yes, there’s no arm64 deb packages yet.
Fortunately, they are not strictly necessary for audio and MIDI input & output, it’s for The Button and Pisound App.
Please check and provide the output of the commands listed here: https://blokas.io/pisound/docs/software/#verifying-it-works
Have you received your Pi 5 and tested it yet? I just received my Pisound w/case and am very excited about putting it to use!

We haven’t received our Pi 5s yet. If anyone already has a Pi 5, it would be great if you could post the results of the commands listed at https://blokas.io/pisound/docs/software/#verifying-it-works.
The full command line output for
curl https://blokas.io/pisound/install.sh | sh on the Pi5 on Raspberry Pi OS Bookworm (it doesn’t run on Bullseye) is:

Now you may run 'sudo pisound-config' to customize your installation!
I see, thanks. It installs on with bookworm 32-bit here, but I can’t see the pisound interface. I tried to run RNBO with the pisound, and I can’t say if it’s related to that or not. But I noticed that the button doesn’t work either…

Finally we received our Pi 5 shipment.
There’s an issue in the kernel that prevents Pisound from working right away on Pi 5, but we’ll work with RPi Foundation to sort the situation out. Sometimes new releases are just shaky at the beginning, no worries.

Ok, here’s a proper temporary workaround, add exactly this at the top of your /boot/config.txt:
dtoverlay=
dtoverlay=pisound

Thanks a lot. I Shows up now. Next step will be to get it to play nicely with RNBO. But that’s for the other forum
There’s a fix in the Raspberry Pi’s kernel tree that will make Pisound work on Raspberry Pi 5 right away, we now have to wait until the next stable update of the kernel gets released.
Great news. Thanks A lot!
Hey!
This makes pisound show up when I use aplay -l, but I’m still having trouble with jack…
I keep getting the following error:
JackPosixProcessSync::LockedTimedWait error usec = 5000000 err = Connection timed out
I’ve already tried updating the kernel as suggested earlier, using the new hat_map.dtb overlay, and updating both JACK (to version 1.9.21) and ALSA, but no luck 
edit: Thought it might help to know, JACK works as expected with a USB Audio Interface, so I don’t suspect the problem is JACK…
edit 2: I’m able to get pisound to work with jackd when I use either the -P or -C flags with jackd but NOT BOTH… Have tested functionality, it seems to work as expected when set on either settings, still struggling to figure out why duplex is failing

Thank you for the information, I can reproduce the problem, we’ll investigate.

There’s a fix for this in RPi kernel, until it’s officially released, temporarily you may use this command to get it:
sudo rpi-update pulls/5757

Pisound should work fine now with Raspberry Pi kernel versions 6.1.64 and greater. Until a new version of raspberrypi-kernel package gets released (which is not done often), you may use this command to get the kernel updated:
sudo rpi-update
