Versões instaladas de libpulse0e 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

Isso parece ser um bug Ubuntu 20.04porque libpulse0a versão 1:13.99.1-1ubuntu3.13já está instalada no sistema, mas conforme descrito na mensagem de erro pulseaudio-module-gsettingse pulseaudio-module-zeroconfdepende libpulse0da versão estritamente igual a 1:13.99.1-1ubuntu3.8(que é menor que a já instalada)

    A instalação manual pulseaudio-module-zeroconfe pulseaudio-module-gsettingscom versões apropriadas como arquivos deb resolveu o problema com dependências para paprefs. Libs para minha configuração que encontrei aqui:

    pacotes deb instalados com comandos:

    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

    ( Como faço para instalar um arquivo .deb através da linha de comando? )

    Depois que a instalação do paprefswith aptfor bem-sucedida:

    sudo apt install paprefs

    Para executar PulseAudio Preferenceso menu:

    paprefs

    Houve um problema com os itens de menu esmaecidos no PulseAudio Preferencesmenu.

    As seguintes informações ajudaram:

    paprefspesquisa módulos existentes, /usr/lib/pulse-13.99/modules/mas Ubuntu 20.04os armazena em /usr/lib/pulse-13.99.1/ solução alternativa rápida:

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

    Informação relacionada:

    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
