Olá,
Sempre que vou ouvir alguma musica, assistir um video local ou no youtube o som trava em alguns trechos, como um disco arranhando.
Abaixo coloco o resultado de alguns comandos:

Alguém poderia me ajudar com esse problema?
Li em alguns topicos que exite algum problema com pulse que causa esse tipo de erro,
mas fiquei com receio de fazer qualquer alteração antes e consultar os mais experientes.
obs1:
alterei arquivo /etc/pulse/default.pa na seguinte linha:
load-module module-udev-detect
para
load-module module-udev-detect tsched=0
mas nao adiantou.
