Cómo restablecer los sonidos en Yosemite 10.10.3

En una versión anterior de OSX, la combinación alt-cmd-P-R vuelve a sonar después de un reinicio, pero no en Yosemite.

En algunas versiones de OSX, el comando sudo killall coreaudio funciona pero no en Yosemite 10.10.3 en una MacBook Air de mediados de 2013. Este problema también se produjo en Yosemite 10.10.1 al actualizar a la nueva versión. Me las arreglé para recuperar sonidos por los procedimientos anteriores.

No veo fuentes de audio en la configuración de sonido después de que apareció este problema, incluso después de esos dos intentos de resolver este problema.

¿CómopuedesrestablecerlossonidosenOSXYosemite10.10.3?

Usé mi Macbook air 3 horas, fui a pausar y abrí el Macbook de nuevo, el mismo problema volvió. Realmente no entiendo la razón de error OSX.

que son bastante nuevos.

El comando kextstat -b com.apple.driver.AudioAUUC da

lo que significa que la cosa de audio no se carga como se discutió con @danielAzuelos.

Podría estar relacionado con el hardware: conecte un auricular a la computadora y asegúrese de que realmente se conecte. Desconéctelo y reinicie. Tenía un MacMini con audio defectuoso y esto me ayudó a mejorarlo por un tiempo. Si no aparece ningún sonido de inicio, intente lo mismo otra vez, pero deje que se conecten los auriculares. Experimente con esto.

Nota: cuando no aparece el timbre de inicio, es probable que esto signifique que el hardware de audio no pudo inicializarse y que todo lo relacionado con el software no puede cambiar nada, ya que el controlador de audio no tiene conexión con el hardware.

Ya que estamos hablando aquí de un componente muy arriesgado del kernel que viene del disco, la primera hipótesis a matar es un sistema de archivos dañado.

Verifique su partición de arranque con la Utilidad de Discos.

Si aparecen errores, repárelos y reinicie.
Verifique el problema de extensión:

Reinicie su Mac sin extensiones: OS X Yosemite: inicie en modo seguro

Si no escuchas el sonido del timbre de arranque, solo presiona ⇧ shift 3 segundos después del botón de encendido. Manténgalo deprimido hasta que vea la barra de progreso gris oscuro que muestra las extensiones, el caché y la reorganización del kernel en progreso.

Comprueba si el sonido es correcto.

Si es así, inicia la búsqueda de la extensión incorrecta.

Si no, tienes un problema de hardware. Lleva tu Mac a Apple.
Compruebe si hay daños en la extensión, el caché o el kernel:

Verifique si las extensiones de kernel de audio están realmente cargadas:
```
kextstat | egrep 'Index|Audio'
```
Debería obtener una salida muy similar (pero el campo de dirección hexadecimal) a esto:
```
$ kextstat | egrep 'Index|Audio'
Index Refs Address            Size       Wired      Name (Version) <Linked Against>
       95    4 0xffffff7f81603000 0x30000    0x30000    com.apple.iokit.IOAudioFamily (203.3) <94 5 4 3 1>
      196    0 0xffffff7f82c24000 0x5000     0x5000     com.apple.driver.AudioAUUC (1.70) <95 76 12 11 7 5 4 3 1>
$
```
Si no tiene estas 2 extensiones cargadas, aprovechará esta configuración predeterminada para cargarlas en un modo en el que verá lo que está mal (es decir, lo que generalmente está oculto detrás del globo de playa agradable ® ).

Para recargar manualmente una extensión faltante y aprovechar esta operación manual para comprender mejor el origen de la falla, aquí se explica cómo proceder:
```
/usr/bin/sudo kextutil -t -v 6 -b com.apple.driver.AudioAUUC
```
que carga la extensión del kernel com.apple.driver.AudioAUUC

-b lo identifica con su nombre de paquete,

-t print diagnostics,

-v 6 será lo más detallado posible sobre cada paso de este proceso.

Al final de esta carga detallada de la extensión del kernel, verifique que el kernel haya cargado esta extensión:
```
kextstat -b com.apple.driver.AudioAUUC
```
