Remova todos os módulos de áudio e instale apenas o ALSA, se quiser, pode tentar pelo script do site oficial.

por favor, quais os pacotes devo desinstalar e instalar novamente?

pelo que entendi eu devo deixar apenas o alsa instalado, entao fui em

http://www.alsa-project.org/main/index.php/Driver_Compilation

e fiz como indicado:

# ./alsa-compile.sh --driver --kmodules

resultado:

eu nao sei como remover os outros modulos de audio e como saber se o alsa já está instalado.

obs1. consegui desinstalar o pulse, porem o icone de volume sumiu da barra superior e em configurações do sistema em som está
desabilitada todas as opções, ou seja, nao consigo controle o volume do som.
obs2. estou testando para observar se o som vai continuar travando.
