<h2>Pipewire</h2>
<h3>2025-04-28</h3>
<h4>Fixing Thinkpad X220 microphone woes</h4>
<p>So with my nice new DWM installation I waltz into a Jitsi meeting only to find that my microphone
wasn't working even though it appeared to. Something was missing in pulseaudio after I removed XFCE4, or
wasn't taken into account in DWM. Then I noticed that Librewolf was looking for Pipewire. What?</p>
<p>Eventually I got it working, but the microphone was distorted and full of parasites.
<a href="/articles/2025/Microphone-distortion-on-Thinkpad-X220.html">Adding a module remap</a> to
turn the two laptop microphones into mono was a tad better but I decided go for the bleeding
edge and install Pipewire instead of Pulseaudio.</p>
<pre>
sudo pacman -Rdd pulseaudio
sudo pacman -S pipewire-{jack,alsa,pulse}
systemctl --user enable --now pipewire pipewire-pulse pipewire-media-session
</pre>
<h4>Noise suppression</h4>
<pre>
git clone https://github.com/werman/noise-suppression-for-voice.git
</pre>
<p>Follow the instructions at <a href="https://github.com/werman/noise-suppression-for-voice">Noise suppression for Voice</a></p>
<p>In order to change the default source:</p>
<pre>
pactl list sources short
pactl set-default-source rnnoise_source
systemctl --user restart pipewire.service
</pre>
<p>And that's the best I'll probably ever get out of the internal X220 microphones.</p>
<p>Why not just use Alsa? Because I use a bluetooth headset and noise suppression.</p>
<p>Why not just use an external microphone? I've ordered one :-)</p>
<h3>Bluetooth Autoconnect</h3>
<p>Just to add, Bluetooth Autoconnect was built for Pulseaudio but works fine with Pipewire.</p>
<p>Bluetooth autoconnect will connect any client that is paired and trusted, in my case a headset.</p>
<p>If you use Chaotic-Aur, pacman -S bluetooth-autoconnect will install it. Use yay -S bluetooth-autoconnect if not.</p>
