    Hello Albert,<br>
    <div class="moz-signature"><br>
      Many thanks for your inputs.<br>
      It's a good news that Purr Data is working fine on rPi 4.
      Hopefully, it should be the same with the new rPi 400.<br>
      <br>
      Q: I have found on OBS <a moz-do-not-send="true"
href="https://download.opensuse.org/repositories/home:/aggraef/Raspbian_10/">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>
      I also noticed on several forums, some people being lost not
      knowing from where to download the latest Purr Data version for
      rPi 4 (Raspberry Pi OS).<br>
      <br>
      Regarding the lousy Audio performance of rPi 4, I will effectively
      use an external USB Audio device.<br>
      Based on my reading, it seems we need to blacklist the internal
      Audio for being able to properly use the external one.<br>
      I'm currently using either <a moz-do-not-send="true"
href="https://www.amazon.fr/dp/B01BNQERRQ/ref=pe_3044141_185740131_TE_item">CSL-1</a>
      or <a moz-do-not-send="true"
href="https://www.amazon.fr/dp/B07MPBVRNF/ref=pe_3044141_185740131_TE_item">CSL-2</a>
      when I need to have a second Audio device under GNU/Linux / ALSA /
      JACK2. Both USB devices are directly recognized by the OSes and
      they are using the same C-Media HS-100B chipset than your UGreen
      Adapter here below.<br>
      <br>
      Now, I will need to wait at least 4-5 weeks before getting my
      Raspberry Pi 400 Kit (AZERTY) as it's currently (already) in stock
      shortage.<br>
      <br>
      Best, Joseph<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"
            moz-do-not-send="true">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>Good luck!</div>

              I'm looking for an additional, very affordable but enough
