Use the correct device name when opening a device by name

[openal-soft.git] / alsoftrc.sample

# OpenAL config file.
#
# Option blocks may appear multiple times, and duplicated options will take the
# last value specified. Environment variables may be specified within option
# values, and are automatically substituted when the config file is loaded.
# Environment variable names may only contain alpha-numeric characters (a-z,
# A-Z, 0-9) and underscores (_), and are prefixed with $. For example,
# specifying "$HOME/file.ext" would typically result in something like
# "/home/user/file.ext". To specify an actual "$" character, use "$$".
#
# Device-specific values may be specified by including the device name in the
# block name, with "general" replaced by the device name. That is, general
# options for the device "Name of Device" would be in the [Name of Device]
# block, while ALSA options would be in the [Name of Device/alsa] block.
# Options marked as "(global)" are not influenced by the device.
#
# The system-wide settings can be put in /etc/openal/alsoft.conf and user-
# specific override settings in $HOME/.alsoftrc.
# For Windows, these settings should go into $AppData\alsoft.ini
#
# 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:

## General stuff

[general]

## disable-cpu-exts: (global)
#  Disables use of specialized methods that use specific CPU intrinsics.
#  Certain methods may utilize CPU extensions for improved performance, and
#  this option is useful for preventing some or all of those methods from being
#  used. The available extensions are: sse, sse2, sse4.1, and neon. Specifying
#  'all' disables use of all such specialized methods.
#disable-cpu-exts =

## drivers: (global)
#  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 (e.g. 'oss,' will try OSS first before
#  other backends, while 'oss' will try OSS only). Backends prepended with -
#  won't be considered for use (e.g. '-oss,' will try all available backends
#  except OSS). An empty list means to try all backends.
#drivers =

## channels:
#  Sets the output channel configuration. If left unspecified, one will try to
#  be detected from the system, and defaulting to stereo. The available values
#  are: mono, stereo, quad, surround51, surround51rear, surround61, surround71
#channels =

## sample-type:
#  Sets the output sample type. Currently, all mixing is done with 32-bit float
#  and converted to the output sample type as needed. Available values are:
#  int8    - signed 8-bit int
#  uint8   - unsigned 8-bit int
#  int16   - signed 16-bit int
#  uint16  - unsigned 16-bit int
#  int32   - signed 32-bit int
#  uint32  - unsigned 32-bit int
#  float32 - 32-bit float
#sample-type = float32

## frequency:
#  Sets the output frequency. If left unspecified it will try to detect a
#  default from the system, otherwise it will default to 44100.
#frequency =

## period_size:
#  Sets the update period size, in frames. This is the number of frames needed
#  for each mixing update. Acceptable values range between 64 and 8192.
#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. Acceptable values
#  range between 2 and 16.
#periods = 4

## stereo-mode:
#  Specifies if stereo output is treated as being headphones or speakers. With
#  headphones, HRTF or crossfeed filters may be used for better audio quality.
#  Valid settings are auto, speakers, and headphones.
#stereo-mode = auto

## hrtf:
#  Controls HRTF processing. These filters provide better spatialization of
#  sounds while using headphones, but do require a bit more CPU power. The
#  default filters will only work with 44100hz or 48000hz stereo output. While
#  HRTF is in use, the cf_level option is ignored. Setting this to true or
#  false will forcefully enable or disable HRTF, otherwise HRTF will be enabled
#  when using headphones.
#hrtf =

## hrtf_tables: (global)
#  Specifies a comma-separated list of files containing HRTF data sets. The
#  format of the files are described in hrtf.txt. The filenames may contain
#  these markers, which will be replaced as needed:
#  %r - Device sampling rate
#  %% - Percent sign (%)
#  The listed files are relative to system-dependant data directories. On
#  Windows this is:
#  $AppData\openal\hrtf
#  And on other systems, it's (in order):
#  $XDG_DATA_HOME/openal/hrtf  (defaults to $HOME/.local/share/openal/hrtf)
#  $XDG_DATA_DIRS/openal/hrtf  (defaults to /usr/local/share/openal/hrtf and
#                               /usr/share/openal/hrtf)
#  An absolute path may also be specified, if the given file is elsewhere.
#hrtf_tables = default-%r.mhr

## 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

## resampler: (global)
#  Selects the resampler used when mixing sources. Valid values are:
#  point - nearest sample, no interpolation
#  linear - extrapolates samples using a linear slope between samples
#  cubic - extrapolates samples using a Catmull-Rom spline
#  Specifying other values will result in using the default (linear).
#resampler = linear

## rt-prio: (global)
#  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

## 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

## 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 =

## excludefx: (global)
#  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,autowah,chorus,
#  compressor,distortion,echo,equalizer,flanger,modulator,dedicated
#excludefx =

## default-reverb: (global)
#  A reverb preset that applies by default to all sources on send 0
#  (applications that set their own slots on send 0 will override this).
#  Available presets are: None, Generic, PaddedCell, Room, Bathroom,
#  Livingroom, Stoneroom, Auditorium, ConcertHall, Cave, Arena, Hangar,
#  CarpetedHallway, Hallway, StoneCorridor, Alley, Forest, City, Moutains,
#  Quarry, Plain, ParkingLot, SewerPipe, Underwater, Drugged, Dizzy, Psychotic.
#default-reverb =

## trap-alc-error: (global)
#  Generates a SIGTRAP signal when an ALC device error is generated, on systems
#  that support it. This helps when debugging, while trying to find the cause
#  of a device error. On Windows, a breakpoint exception is generated.
#trap-alc-error = false

## trap-al-error: (global)
#  Generates a SIGTRAP signal when an AL context error is generated, on systems
#  that support it. This helps when debugging, while trying to find the cause
#  of a context error. On Windows, a breakpoint exception is generated.
#trap-al-error = false

## MIDI stuff (EXPERIMENTAL)
##
[midi]

## soundfont: (global)
#  A default soundfont (sf2 format). Used when an app requests the system
#  default. The listed file is relative to system-dependant data directories.
#  On Windows this is:
#  $AppData\openal\soundfonts
#  And on other systems, it's (in order):
#  $XDG_DATA_HOME/openal/soundfonts
#  $XDG_DATA_DIRS/openal/soundfonts
#  An absolute path may also be specified, if the given file is elsewhere.
#soundfont =

## volume: (global)
#  Additional attenuation applied to MIDI output, expressed in decibels. This
#  is used to help keep the mix from clipping, and so must be 0 or less. The
#  value is logarithmic, so -6 will be about half amplitude, and -12 about
#  1/4th. The default is roughly -13.9794 (0.2, or 1/5th).
#volume =

##
## Reverb effect stuff (includes EAX reverb)
##
[reverb]

## boost: (global)
#  A global amplification for reverb output, expressed in decibels. The value
#  is logarithmic, so +6 will be a scale of (approximately) 2x, +12 will be a
#  scale of 4x, etc. Similarly, -6 will be about half, and -12 about 1/4th. A
#  value of 0 means no change.
#boost = 0

## emulate-eax: (global)
#  Allows the standard reverb effect to be used in place of EAX reverb. EAX
#  reverb processing is a bit more CPU intensive than standard, so this option
#  allows a simpler effect to be used at the loss of some quality.
#emulate-eax = false

##
## PulseAudio backend stuff
##
[pulse]

## spawn-server: (global)
#  Attempts to autospawn a PulseAudio server whenever needed (initializing the
#  backend, enumerating devices, etc). Setting autospawn to false in Pulse's
#  client.conf will still prevent autospawning even if this is set to true.
#spawn-server = true

## allow-moves: (global)
#  Allows PulseAudio to move active streams to different devices. Note that the
#  device specifier (seen by applications) will not be updated when this
#  occurs, and neither will the AL device configuration (sample rate, format,
#  etc).
#allow-moves = false

## device: (global)
#  Sets the device name for the default playback device.

#  device index for the requested device name.
#device-prefix = plughw:

#capture-prefix- =

## mmap:
#  Sets whether to try using mmap mode (helps reduce latencies and CPU
#  consumption). If mmap isn't available, it will automatically fall back to
#  non-mmap mode. True, yes, on, and non-0 values will attempt to use mmap. 0
#  and anything else will force mmap off.

[jack]

## spawn-server: (global)
#  Attempts to autospawn a JACK server whenever needed (initializing the
#  backend, opening devices, etc).
#spawn-server = false

## buffer-size:
#  Sets the update buffer size, in samples, that the backend will keep buffered
#  to handle the server's real-time processing requests. This value must be a
#  power of 2, or else it will be rounded up to the next power of 2. If it is
#  less than JACK's buffer update size, it will be clamped. This option may
#  be useful in case the server's update size is too small and doesn't give the
#  mixer time to keep enough audio available for the processing requests.
