Q: I have found on OBS <a href="https://download.opensuse.org/repositories/home:/aggraef/Raspbian_10/" target="_blank">your
Rapsbian_10 link</a> for downloading
'purr-data_2.15.2+git4757+2d04705d-1.debian.tar.xz' (as of
03-Nov-2020). Is it the good one?<br></div></div></blockquote><div><br></div><div>Yep, that's the one. But I'd recommend using the package repository so that you get automatic updates and all the dependencies. See the instructions in the wiki at <a href="https://github.com/agraef/purr-data/wiki/Installation#raspbian">https://github.com/agraef/purr-data/wiki/Installation#raspbian</a>. Also note that those packages will only work on a stock (32 bit) Raspbian, not on one of the 64 bit flavors that can be found on the web.<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 external one.<br></div></div></blockquote><div><br></div><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></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>

when I need to have a second Audio device under GNU/Linux / ALSA /

<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>
