No hay sonido

(When Debian PC can not play any sound)

Derechos Reservados © 2017; Lab. IT Y TI.

Por alguna falla en la terminación de algún programa reproductor de sonido, posteriormente, las aplicaciones que se ejecutan posteriormente no son capaces de reproducir la señales de audio.

Lo primero que uno debe asegurar es que no esté silenciado el reproductor de sonido (mute), lo cual puede verificarse con la interfaz gráfica del mezclador, o con el applet correspondiente al mezclador ejecutado en algún panel del escritorio. Como en el sistema pueden coexistir varios mezcladores y varios dispositivos de sonido, uno debe verificar todas las posibilidades. Por ejemplo, si no se ha aplicado el silenciador al reproductor de video.

La finalidad principal del mezclador de sonido (alsa, pulseaudio, etc) es que sólo él tenga acceso directo a la tarjeta de sonido, mientras sirve de interfaz para los demás programas. En interés de la simplicidad, puede uno remover, por ejemplo, pulseaudio, y quedarse sólo con alsa, aunque no es indispensable.

Si aún no ha resuelto el problema, uno puede ejecutar el programa de diagnóstico speaker-test.

Ejemplo de diagnóstico:

___________________________

phantasticum@machina:~$ sudo su [sudo]

password for phantasticum:

root@machina:/home/phantasticum# speaker-test -Dplug:front -c2

speaker-test 1.0.28

Playback device is plug:front

Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise

Playback open error: -16,Device or resource busy

___________________________

En relación con el último mensaje, uno puede imaginar que existe un archivo "lock" que impide el acceso al dispositivo. No siempre es el caso, lo que es congruente con el texto del mensaje: "Device OR resource".  A veces sucede que alguno de los registros de la tarjeta de sonido tiene la marca de ocupada, y la solución es reiniciarla. Curiosamente, reiniciar el sistema no resuelve el problema.

Uno puede reiniciar  la tarjeta de sonido  con el programa alsactl, como se muestra a continuación:
_____________________________________

root@machina:/home/phantasticum#  alsactl init

Found hardware: "HDA-Intel" "Realtek ALC1200"
"HDA:10ec0888,103c2a6f,00100101" "0x103c" "0x2a6f"

Hardware is initialized using a generic method

root@machina:/home/phantasticum

 ___________________________

Por supuesto, alsactl  tiene más funciones, las cuales puede ver en el manual del sistema, pero la descrita suele resolver el irritante problema de no tener ningún sonido.

Comunicación vía USB entre un teléfono con Android, o un reproductor multimedia, y una computadora bajo Linux Debian

( Telephone to / from Computer communication via USB cable)

 

Cuando uno instala Debian, uno escoge si quiere cargar una gran cantidad de manejadores de periféricos, o bien, si solamente instala los necesarios para aquellos periféricos presentes durante el proceso de instalación. Así que es posible que necesite instalar algunos paquetes: ¿cuáles?

 

Lo primero que debe saber es que la transferencia entre Android y Linux se lleva a cabo mediante el protocolo MTP: Media Transfer Protocol. Este protocolo define una clase de dispositivo USB usado por muchos teléfonos móbiles ( todos los teléfonos Windows Phone 7, 8 y 10, los teléfonos Android más nuevos, y muchos Reproductores multimedia (Media Players)

 

1) En los repositorios de Debian uno encuentra por lo menos los siguientes paquetes [ 1 ] para comunicarse con el teléfono o reproductor:

 

mtp-tools: Media Transfer Protocol (MTP) library tools

gmtp: simple file transfer program for MTP based devices

 

2) Conviene mucho que los usuarios puedan montar por sí mismos ya sea un teléfono o un reproductor de medios, para lo cual necesita instalar para ellos un Sistema Virtual de Archivos en el Espacio de Usuarios:

 

gvfs-backends: userspace virtual filesystem - backends

(Estos backends de GNOME incluyen al proceso «gvfsd-mtp»)

 

ó

 

jmtpfs: FUSE based filesystem for accessing MTP devices

 

También se requerirán las programotecas:

 

libmtp-common: Media Transfer Protocol (MTP) common files

libmtp-runtime: Media Transfer Protocol (MTP) runtime tools

libmtp9: Media Transfer Protocol (MTP) library

 

Previo a la conexión del teléfono, tome en cuenta lo siguiente:


1) Normalmente, para comunicación con el teléfono NO es indispensable que la tarjeta SIM esté instalada.

 

2) Se recomienda conectar el cable USB entre teléfono y la computadora cuando el teléfono está apagado; sin embargo, el teléfono no será reconocido por la computadora hasta que lo encienda.

 

3) En caso de que tenga algún problema de comunicación, por ejemplo, que el teléfono no se monte (que no se liste en el panel lateral de algún navegadores de archivos), verifique que la computadora ya detectó el teléfono, por medio del comando «lsusb». Si la respuesta al comando no enlista al teléfono, verifique que el cable conector funcione correctamente.

 

Ejemplo:

 

phantasticum@machina:~$ lsusb

 

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 006 Device 003: ID 1bcf:0005 Sunplus Innovation Technology Inc.

Bus 006 Device 002: ID 0c45:7603 Microdia

Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 003: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

Luego puede verificar datos del teléfono como se ilustra con el siguiente ejemplo:

 

Ejemplo de salida de la herramienta mtp-detect:

 

Primero, es mejor si utiliza un directorio dentro de su espacio de usuario para que contenga los resultados, tal como:

 

/home/phantasticum/Documents/MySpyPhone

 

Ya que la detección resulta en una buena cantidad de “taquigrafía”; luego, para conservar los datos, redirija la salida a un archivo de texto tal como:

 

deteccion-galaxy.txt

 

phantasticum@machina:~/Documents/MySpyPhone/$ mtp-detect > deteccion-galaxy.txt

Unable to read MTPZ public exponent from ~/.mtpz-data, MTPZ disabled.

Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).

phantasticum@machina:~/Documents/MySpyPhone/$

 

Ahora puede visualizar la salida del comando antes de montar el teléfono en el sistema de archivos:
