PiSound 1.0 with Raspberry Pi 4 B

[FullHorst]

Hello!

Is anyone using this combination with no problems? Do you use a cooler?

I wanna update from my Pi Model 3B

I’m aware of this thread, mentioning an issue caused by a power supply design change in Raspbery Pi 4. Is this still up to date?

PiSound with Raspberry Pi 4

Regarding the Pi 4 reboot issue with Pisound, the issue seems to be a change of how the 3.3V supply on the GPIO header of Raspberry Pi 4 works - it now gets turned on with a 60ms delay, while 5V supply is available immediately, and during shutdown and reboot it gets turned off. 3.3V power supply on earlier Rasbperry Pi models was getting turned on nearly instantly. There’s a temporary workaround available, consisting of 2 parts: Firmware EEPROM config update: Download the bootloader from h…

Cheers!

ah, seems like this is making the workaround obsolete

PiSound with Raspberry Pi 4

Since pisound-btn version 1.11, there’s a new menu in sudo pisound-config for making it easy to manage the software workaround for reboots on Pi 4 and checking whether your Pisound version has a hardware workaround for the power supply design change in Raspberry Pi 4 (since Pisound hardware version v1.1): [image] Once Pisound is back in stock, they’ll be the v1.1 ones. You can get the latest version of pisound-btn by running: sudo apt update && sudo apt install pisound-btn

You can freely use Pisound v1.0 with Pi 4 or Pi 5. If you hit the stuck on reboot issue as mentioned in the thread you linked, I’d recommend enabling the software workaround as described.

In our experience, Pi 5 works best with an active fan, Pi 4 can do ok without it. They fit best under v1.2 Pisound.

Thanks for the fast reply!

Latency is just a bit too high for me right now, and I also have problems with restarting the device. And two out of five times midi is not working on startup

I just don’t come to a point where the PiSound is working 100% reliably for me, and I would need that in a live situation. I wanna use it as a Pure Data live effect box

I would hope that an update to a Rasp 4 B would solve those problems

[Giedrius]

It would help with the speed side of things. The other problems you list sound like they originate in software configuration.

@FullHorst when I used a RPi4 with PiSound I added the Pimorini Fan Shim to help keep the setup cool.

Fan SHIM for Raspberry Pi

If you decide to go this route don’t install the software, just let the fan run. Using this setup I never had any reliability issues and I used that live every week.

I’ve since upgraded to a RPi5 with active cooler with the newer PiSound. Love it! If you can swing the 5 with the active cooler and the new PiSound it certainly helps, especially when running NAM in MODEP.

My RPi 3B starts fine when I reboot. But I have to wait a little until I can turn it on again, after turning it off

With midi, I use mzeros latest midiminder. Sometimes it takes a few restarts to make it work. It’s just that the signals aren’t received in Pure Data

maybe, I should do this

Can't install PureData module

Fixed this in patchbox-cli package, the fix is available since version 1.4.0-5. You can run: sudo apt update sudo apt install patchbox-cli to get the fix.

instead of what I did

Patchbox Pure data module errors

I know this is an old thread but in case this is helpful for someone in the future, this is how I resolved this same issue for myself. Full disclosure: I’m a total linux newb, so some of this might not have been necessary or may’ve even been done incorrectly. I cobbled the solution together from other forum posts. This is an error caused by the admidiminder service. You will need to edit the patchbox module config file located at /usr/local/patchbox-modules/puredata/patchbox-module.json There …

thanks for the info! does the fan fit inside the Pisound case?

[jtemple967]

@FullHorst yes, it does indeed fit inside the case. The only modification might be to remove the standoffs in that corner or find some standoffs of varying height.

I’m using Pisound for analogue sound capture from my vinyl player. After AD conversion it is streamed to Apple HomePods in my household.
The pisound + RPI 4B unit is contained in the Blokas Pisound Case. No cooling.

I have no problem with overheating whatsoever.

@TomEriksen curious as to how you’re feeding the vinyl signal into your pi. New turntable with a line out?

[TomEriksen]

Yes I use the Pro-ject Primary E Phono. It has a built in RIAA amplifier. The unamplified signal from the pickup is ≈60 dB weaker. It will not work.

Sure, the gain on the pisound can be cranked up 40dB, but when I use the direct feed from the pickup I get a lot of 50Hz static from the turntable.
