P.S Я извиняюсь за громоздкое сообщение, но как не парился теги [[«cut»]]text[[«/cut»]] не работают ((

Здравствуйте уважаемые форумчане! Прошу вас помочь по моей проблеме. Имеется: Радиостудия, с неё уходит звук на плату в линейный вход компа на Ubuntu 8.04.4 На компе с Ubuntu 8.04.4 звук со входа забирает darkice и монтирует его в Icecast тем самым создавая поток. Далее>>>> В нескольких километрах, на передающем центре, откуда непосредственно ведется вещание радиостанции на FM\AM Стоит 2 компа на Ubuntu server 12.04.01 На них установлен mpd+mpc. Связь между передающим центром и радиостудией осуществляется через внутреннюю сеть одного провайдера. На серверах на передающем mpc грузит плейлист в котором есть несколько пунктов. 1.Поток с сервера со студии. 2.Московский поток того-же радио (без наших трансляций). 3.Поток с сервера со студии по резервному провайдеру (на студии 2 провайдера).

Очень часто, почти каждую ночь плеер на передающем центре спрыгивает с 1го пункта плейлиста и начинает проигрывать московский поток. Сначало думал что проблемы в провайдере, на передающем и в студии запустил скрипт который пингует: 1.Студия пингует комп на передающем центре, пингует гугль, пингует яндекс, пингует новосиб. 2. Передающий пингует студию, гугль, яндекс, новосиб. И если пинг не прошел по какому-либо из ресурсов, скрипт записывает время неудачного пинга в ping_bad.log

Что самое интересное, это то что плеер переключается ночью со студийного потока на московский, причем никаких «бэд пингов» не записывает, инет не обрывается.

Вот скачок на московский поток 13 ноября в 23.50 в логах mpd пишет следующее.

Вот мой конфиг mpd:

# An example configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.


# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory		"/var/lib/mpd/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory		"/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file			"/var/lib/mpd/tag_cache"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
log_file			"/var/log/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file			"/var/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.
#
state_file			"/var/lib/mpd/state"
#
###############################################################################


# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
user				"mpd"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon.
#
# For network
bind_to_address		"0.0.0.0"
#
# And for Unix Socket
#bind_to_address		"/var/run/mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
#port				"6600"
#
# This setting controls the type of information which is logged. Available 
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
log_level			"verbose"
#
# If you have a problem with your MP3s ending abruptly it is recommended that 
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available from <http://www.willwap.co.uk/Programs/vbrfix.php>), at which
# point gapless MP3 playback can be enabled.
#
gapless_mp3_playback			"yes"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists	"no"
#

#
###############################################################################


# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following 
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks	"yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks		"yes"

#
###############################################################################


# Volume control mixer ########################################################
#
# These are the global volume control settings. By default, this setting will
# be detected to the available audio output device, with preference going to 
# hardware mixing. Hardware and software mixers for individual audio_output
# sections cannot yet be mixed.
#
# An example for controlling an ALSA, OSS or Pulseaudio mixer; If this
# setting is used other sound applications will be affected by the volume
# being controlled by MPD.
#
#mixer_type			"hardware"
#
# An example for controlling all mixers through software. This will control
# all controls, even if the mixer is not supported by the device and will not
# affect any other sound producing applications.
#
#mixer_type			"software"
#
# This example will not allow MPD to touch the mixer at all and will disable
# all volume controls.
#
#mixer_type			"disabled"
#
###############################################################################


# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "album" or "track". See <http://www.replaygain.org> for more

# result in the volume of all playing audio to be adjusted so the output has 
# equal "loudness". This setting is disabled by default.
#
#volume_normalization		"no"
#
###############################################################################


# MPD Internal Buffering ######################################################
#
# This setting adjusts the size of internal decoded audio buffering. Changing
# this may have undesired effects. Don't change this if you don't know what you
# are doing.
#
#audio_buffer_size		"2048"
#
# This setting controls the percentage of the buffer which is filled before 
# beginning to play. Increasing this reduces the chance of audio file skipping, 
# at the cost of increased time prior to audio playback.
#
#buffer_before_play		"10%"
#
###############################################################################


# Resource Limitations ########################################################
#
# These settings are various limitations to prevent MPD from using too many

Суть проблемы: 1.Как понять что является причиной переключения потоков? 2.Как можно сделать чтоб при пропаже потока со студии mpc плеер переключался на московский поток и «мониторил» появление потока со студии, а как поток со студии появлялся, mpc автоматом переходил на него?

и что за бредовая строчка в mpd.log Nov 13 23:50 : can't find alsa mixer control «PCM» когда в конфиге mpd использование PCM в комментах?

Заранее вам большое спасибо! Надеюсь на вашу помощь.

Так пройдут пустые строки. Лучше так: grep '^[^#]' filename
