[openAL] pas de son

Message par ilovechocolat »

Bonjours a tous !

Je suis sous Archlinux 64bit, comme je développe un peut j'ai décidé d'utiliser la library openAL pour gérer le son, mais aucun son n'est émis.

Le problème ne vient pas de mon code car il fonctionne très bien sur mon netbook (lui même sous Archlinux mais en 32bit) avec le même programme, la même musique ...

Je suppose donc que cela vient d'un problème de configuration de openAL, mais comme je connais assez mal cette library j'ai besoin de votre aide.

Voici mon /etc/openal/alsoft.conf :

Code : Tout sélectionner

# OpenAL config file. Options that are not under a block or are under the
# [general] block are for general, non-backend-specific options. Blocks may
# appear multiple times, and duplicated options will take the last value
# specified.
# The system-wide settings can be put in /etc/openal/alsoft.conf and user-
# specific override settings in ~/.alsoftrc.
# For Windows, these settings should go into %AppData%\alsoft.ini
# The environment variable ALSOFT_CONF can be used to specify another config
# override

# Option and block names are case-insenstive. The supplied values are only
# hints and may not be honored (though generally it'll try to get as close as
# possible). Note: options that are left unset may default to app- or system-
# specified values. These are the current available settings:

## format:
#  Sets the output format. Can be one of:
#  AL_FORMAT_MONO8    (8-bit mono)
#  AL_FORMAT_STEREO8  (8-bit stereo)
#  AL_FORMAT_QUAD8    (8-bit 4-channel)
#  AL_FORMAT_51CHN8   (8-bit 5.1 output)
#  AL_FORMAT_61CHN8   (8-bit 6.1 output)
#  AL_FORMAT_71CHN8   (8-bit 7.1 output)
#  AL_FORMAT_MONO16   (16-bit mono)
#  AL_FORMAT_STEREO16 (16-bit stereo)
#  AL_FORMAT_QUAD16   (16-bit 4-channel)
#  AL_FORMAT_51CHN16  (16-bit 5.1 output)
#  AL_FORMAT_61CHN16  (16-bit 6.1 output)
#  AL_FORMAT_71CHN16  (16-bit 7.1 output)
#  AL_FORMAT_MONO32   (32-bit float mono)
#  AL_FORMAT_STEREO32 (32-bit float stereo)
#  AL_FORMAT_QUAD32   (32-bit float 4-channel)
#  AL_FORMAT_51CHN32  (32-bit float 5.1 output)
#  AL_FORMAT_61CHN32  (32-bit float 6.1 output)
#  AL_FORMAT_71CHN32  (32-bit float 7.1 output)
format = AL_FORMAT_STEREO16

## cf_level:
#  Sets the crossfeed level for stereo output. Valid values are:
#  0 - No crossfeed
#  1 - Low crossfeed
#  2 - Middle crossfeed
#  3 - High crossfeed (virtual speakers are closer to itself)
#  4 - Low easy crossfeed
#  5 - Middle easy crossfeed
#  6 - High easy crossfeed
#  Users of headphones may want to try various settings. Has no effect on non-
#  stereo modes.
cf_level = 0

## head_dampen:
#  Sets the amount of dampening on sounds emanating from behind the listener.
#  This is used to simulate the natural occlusion of the head, which is
#  typically missing with mono and stereo output, and as such, only works on
#  mono and stereo output modes. Valid values range from 0 to 1 (inclusive),
#  and higher values provide a stronger effect.
head_dampen = 0.25

## frequency:
#  Sets the output frequency.
frequency = 44100

## resampler:
#  Selects the resampler used when mixing sources. Valid values are:
#  0 - None (nearest sample, no interpolation)
#  1 - Linear (extrapolates samples using a linear slope between samples)
#  2 - Cubic (extrapolates samples using a Catmull-Rom spline)
#  Specifying other values will result in using the default (linear).
resampler = 1

## rt-prio:
#  Sets real-time priority for the mixing thread. Not all drivers may use this
#  (eg. PortAudio) as they already control the priority of the mixing thread.
#  0 and negative values will disable it. Note that this may constitute a
#  security risk since a real-time priority thread can indefinitely block
#  normal-priority threads if it fails to wait. As such, the default is
#  disabled.
rt-prio = 0

## period_size:
#  Sets the update period size, in frames. This is the number of frames needed
#  for each mixing update.
period_size = 1024

## periods:
#  Sets the number of update periods. Higher values create a larger mix ahead,
#  which helps protect against skips when the CPU is under load, but increases
#  the delay between a sound getting mixed and being heard.
periods = 4

## sources:
#  Sets the maximum number of allocatable sources. Lower values may help for
#  systems with apps that try to play more sounds than the CPU can handle.
sources = 256

## stereodup:
#  Sets whether to duplicate stereo sounds on the rear and side speakers for 4+
#  channel output. This provides a "fuller" playback quality for 4+ channel
#  output modes, although each individual speaker will have a slight reduction
#  in volume to compensate for the extra output speakers. True, yes, on, and
#  non-0 values will duplicate stereo sources. 0 and anything else will cause
#  stereo sounds to only play out the front speakers. This only has an effect
#  when a suitable output format is used (ie. those that contain side and/or
#  rear speakers).
stereodup = true

## scalemix:
#  Sets whether to scale the remixed output. When the final mix is written to
#  the device, the multi-channel data is remixed so pure-virtual channels (eg.
#  front-center on stereo output) are remixed and added to available channels
#  (eg. front-left and front-right). Scaling helps ensure that no single source
#  will put out more than 100% on a given physical channel. This can cause a
#  noticeable reduction in overall volume, however, so it is off by default.
scalemix = false

## drivers:
#  Sets the backend driver list order, comma-seperated. Unknown backends and
#  duplicated names are ignored. Unlisted backends won't be considered for use
#  unless the list is ended with a comma (eg. 'oss,' will list OSS first
#  followed by all other available backends, while 'oss' will list OSS only).
#  Backends prepended with - won't be available for use (eg. '-oss,' will allow
#  all available backends except OSS). An empty list means the default.
# drivers = pulse,alsa,oss,solaris,dsound,winmm,port,null,wave
drivers = alsa

## excludefx:
#  Sets which effects to exclude, preventing apps from using them. This can
#  help for apps that try to use effects which are too CPU intensive for the
#  system to handle. Available effects are: eaxreverb,reverb,echo,modulator
excludefx =

## slots:
#  Sets the maximum number of Auxiliary Effect Slots an app can create. A slot
#  can use a non-negligible amount of CPU time if an effect is set on it even
#  if no sources are feeding it, so this may help when apps use more than the
#  system can handle.
slots = 4

## sends:
#  Sets the number of auxiliary sends per source. When not specified (default),
#  it allows the app to request how many it wants. The maximum value currently
#  possible is 4.
sends =

## layout:
#  Sets the virtual speaker layout. Values are specified in degrees, where 0 is
#  straight in front, negative goes left, and positive goes right. Unspecified
#  speakers will remain at their default positions (which are dependant on the
#  output format). Available speakers are back-left(bl), side-left(sl), front-
#  left(fl), front-center(fc), front-right(fr), side-right(sr), back-right(br),
#  and back-center(bc).
layout =

## layout_*:
#  Channel-specific layouts may be specified to override the layout option. The
#  same speakers as the layout option are available, and the default settings
#  are shown below.
#layout_STEREO = fl=-90, fr=90
#layout_QUAD   = fl=-45, fr=45, bl=-135, br=135
#layout_51CHN  = fl=-30, fr=30, fc=0, bl=-110, br=110
#layout_61CHN  = fl=-30, fr=30, fc=0, sl=-90, sr=90, bc=180
#layout_71CHN  = fl=-30, fr=30, fc=0, sl=-90, sr=90, bl=-150, br=150
