Okay. I will need to check if the Raspberry Pi OS delivered with the
rPi 400 is a 32 or 64-bit OS. Currently on the download page of the
Foundation it's a 32-bit.<br></div></blockquote><div><br></div><div>Yep, that's the official distribution, it used to be called Raspbian before.<br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>
In the meantime I'm learning that now <a href="https://manjaro.org/downloads/arm/raspberry-pi-4/arm8-raspberry-pi-4-kde-plasma/" target="_blank">Manjaro</a>
(20.10) and <a href="https://ubuntu.com/download/raspberry-pi" target="_blank">Ubuntu Desktop</a>
(20.10) are official versions for the rPi 4 / rPi 400, but both are
only in 64-bit. So based on above they will not be compatible with
the current Purr Data for rPi.<br></div></blockquote><div><br></div><div>No, they won't. But the OBS has aarch64 build targets for both Manjaro and Ubuntu. I'm not sure whether these will work, but if anyone is willing to test them out, just let me know and I'll enable these targets.</div><div><br></div><div>Albert<br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>

<div>Based on my reading, it seems we need to blacklist
the internal Audio for being able to properly use the

<div>You don't have to do any of that. Just plug the USB
device into the Pi, configure it as the ALSA (or Jack) audio
I/O and you should be set. That way you can keep using the
built-in soundcard for other purposes. If you disable the
built-in soundcard then may run into trouble because Purr
and other applications will fight over access to the device.<br>

I will do it.<br>

<div>Hi Joseph,</div>
<div><br>
</div>
<div>Last time I tested Purr on the Pi4, it worked
fine there. That was quite some time ago, though
(probably around Purr 2.9/2.10), so you'll have to
give it a go yourself to see how well the latest
version works there.</div>
<div><br>
</div>
<div> The only issue I remember was with the rather
lousy built-in soundcard of the Pi4, which can be
overcome with a cheap external USB audio device
(e.g., <a href="https://www.amazon.fr/UGREEN-Adaptateur-Compatible-Raspberry-Microphone/dp/B01N905VOY" target="_blank">https://www.amazon.fr/UGREEN-Adaptateur-Compatible-Raspberry-Microphone/dp/B01N905VOY</a>
is the one that I often use, but any half-decent USB
sound device should do the trick).</div>
<div><br>
</div>
<div>Good luck!</div>

<div> Hello to the List,<br>
<div><br>
I'm looking for an additional, very affordable
but enough powerful PC under GNU/Linux for CAM
(computer-aided music), Programming, Home
automation, etc.<br>
<br>
Currently my choice is going for the <a href="https://www.raspberrypi.org/products/raspberry-pi-400/?resellerType=home" target="_blank">very
new Raspberry Pi 400</a> with Raspberry Pi OS,
a Raspberry Pi 4 that has been integrated into a
keyboard, with a complete kit priced at ~ 100 €
here in Europe (106.50 € Tax incl. in France).<br>
<br>
Questions:<br>
- Has anyone tested Purr Data with the Raspberry
Pi 4 (Debian or other distros)?<br>
- If yes, what was your experience, pros and
cons?<br>
<br>
Thanks a lot.<br>
