¿Cómo puedo hacer que mi sonido funcione?

He intentado hacer que mi sonido funcione en mi escritorio Ubuntu 14.04, pero se niega a funcionar. He mirado por todas partes, pero mi sonido permanece apagado.

ajustes de sonido

La configuración de sonido no me permite subir el volumen de salida. Y mis auriculares no funcionan. He intentado alsamixer y pulseaudio me da un error extraño.

cáscara

1. Si instaló ALSA, la mezcladora ALSA está configurada para silenciar de forma predeterminada y debe ser desactivada después de la instalación antes de poder utilizarla.

En cuanto al error, dice que puseaudio ya se está ejecutando, por lo que no puede iniciar o crear un pid para el daemon como ya existe porque el daemon está en uso. Para reiniciar pulseaudio, use los siguientes comandos:

sudo service pulseaudio stop sudo alsa force-reload sudo service pulseaudio start 

En las versiones más nuevas de ubuntu, ejecute lo siguiente:

 sudo killall pulseaudio sudo alsa force-reload pulseaudio --start --log-target=syslog 

2. Verifique si tiene un archivo en /etc/pulse/default.pa

Si no tienes uno, usa los siguientes comandos

 sudo gedit 

luego, copie y pegue lo siguiente en gedit y luego “guardar como” /etc/pulse/default.pa.

Cuando haya terminado, guarde cualquier trabajo no guardado y reinicie, y debería tener más que una salida ficticia después de volver a iniciar sesión.

Lo siguiente es para 14.04.
