			<description><![CDATA[<p>If you&#039;re experiencing no sound after a system update, try the following steps:</p><p>Check audio settings: Ensure the correct output device is selected.<br />Restart your computer: Sometimes a simple restart can fix the issue.<br />Update or reinstall audio drivers: Go to Device Manager and update your sound drivers, or reinstall them.<br />Run the audio troubleshooter: Use the built-in troubleshooter in your system settings to detect and fix problems.<br />Check for updates: Look for any pending updates that might fix the issue.</p>]]></description>

			<description><![CDATA[<p>原因<br />PulseAudio和Pipewire经常同时安装到系统中，于是gentoo对其各自增加了USE标志，由用户来控制使用哪一个作为声音服务。</p><p>解决<br />cd /etc/portage/package.use/<br />touch ./list&#160; &#160; &#160;##同目录底下还有一个zz-autounmask文件，list是自己的<br />我是使用PipeWire作用声音服务的，所以需要在/etc/portage/package.use/list中添加</p><p>media-video/pipewire sound-server<br />media-sound/pulseaudio -daemon<br />如果是使用PulseAudio作为声音服务,则在/etc/portage/package.use/list中添加</p><p>media-video/pipewire -sound-server<br />media-sound/pulseaudio daemon<br />然后更新系统</p><p>emerge -a -uvDU @world<br />最后重启下pipewire.socket pipewire-pulse.socket或者pulseaudio.service pulseaudio.socket</p>]]></description>
