To my dismay the internal microphone was not recognized at all in any of the sound settings. Finding a solution took a couple hours of reading logs and Googling so I’m putting that knowledge here to helpfully help anyone else in the same situation.</p> <h2 id="the-issue">The Issue</h2> <p>In the Ubuntu setting I was unable to find any recording devices. However, running the command: <code>lspci -knn | grep Audio</code> I was able to see three devices. Notably I saw:</p> <pre class="giallo z-code"><code data-lang="plain"><span class="giallo-l"><span>c3:00.5 Multimedia controller [0480]: Advanced Micro Devices, Inc.

Specifically <a rel="external" href="https://bbs.archlinux.org/viewtopic.php?id=294307">this post on the Archlinux Forums</a>. The answer is to add a file to <code>/etc/modules-load.d/</code> in order to load the correct kernel modules for the internal mic. The exact command the author of the post gave (which worked great for me) is:</p> <pre class="giallo z-code"><code data-lang="plain"><span class="giallo-l"><span>echo -e &quot;snd-pci-ps\nsnd-soc-ps-mach&quot; | sudo tee /etc/modules-load.d/sound.conf &gt; /dev/null</span></span></code></pre> <p>After that I rebooted, and my mic is working great.</p> Quick fix for the internal microphone not being recognized on a Lenovo T14s Gen 4 with AMD Ryzen 7840U running Ubuntu 24.04.
