如何安装 paprefs（PulseAudio 首选项）

Ubuntu 20.04

安装paprefs出现以下错误：

sudo apt install paprefs
The following packages have unmet dependencies:
 paprefs : Depends: pulseaudio-module-gsettings but it is not going to be installed
           Depends: pulseaudio-module-zeroconf but it is not going to be installed

已安装的版本libpulse0和pulseaudio：

apt list libpulse0 # check installed version of libpulse0
libpulse0/now 1:13.99.1-1ubuntu3.13 amd64 [installed,local]
libpulse0/focal-security 1:13.99.1-1ubuntu3.8 i386

apt list pulseaudio
pulseaudio/now 1:13.99.1-1ubuntu3.13 amd64 [installed,local]
pulseaudio/focal-security 1:13.99.1-1ubuntu3.8 i386

这似乎是个错误，Ubuntu 20.04因为系统中已经安装了libpulse0版本，但如错误消息中所述，并且依赖于版本严格等于（小于已安装的版本）1:13.99.1-1ubuntu3.13pulseaudio-module-gsettingspulseaudio-module-zeroconflibpulse01:13.99.1-1ubuntu3.8

手动安装适当版本的 debpulseaudio-module-zeroconf文件pulseaudio-module-gsettings解决了 .Libs 依赖问题，paprefs针对我的配置我在这里找到了：

使用命令安装的 deb 包：

sudo dpkg -i pulseaudio-module-zeroconf_13.99.1-1ubuntu3.13_amd64.deb
sudo dpkg -i pulseaudio-module-gsettings_13.99.1-1ubuntu3.13_amd64.deb

（如何通过命令行安装 .deb 文件？）

安装paprefs成功后apt：

sudo apt install paprefs

运行PulseAudio Preferences菜单：

paprefs

PulseAudio Preferences菜单中的菜单项显示为灰色存在问题。

以下信息有帮助：

paprefs搜索现有模块/usr/lib/pulse-13.99/modules/但Ubuntu 20.04将其存储在/usr/lib/pulse-13.99.1/ 快速解决方法中：

sudo ln -s /usr/lib/pulse-13.99.1/ /usr/lib/pulse-13.99

相关信息：

I discovered the PulseAudio version (to set the 2nd arg to symlink cmd) with pactl --version.
I just have to remember to update the link after running apt-upgrade :-(

pactl --version
pactl 13.99.1
Compiled with libpulse 13.99.0
Linked with libpulse 13.99.0
--
paprefs would have never worked for pulseaudio versions x.y.z ( options would be grayed out )
It works only if pulseaudio version is x.y

来源：全新安装时所有选项均呈灰色 - Ubuntu Studio 20.20
