># 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
>
># 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:
>
>## 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, surround61, surround71
>channels = stereo
>
>## 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

>## hrtf:
>#  Enables HRTF filters. These filters provide for better sound spatialization
>#  while using headphones. The default filter will only work when output is
>#  44100hz stereo. While HRTF is active, the cf_level option is disabled.
>#  Default is disabled since stereo speaker output quality may suffer.
>#hrtf = false
>
>## hrtf_tables
>#  Specifies a comma-separated list of files containing HRTF data sets. The
>#  listed data sets can be used in place of or in addiiton to the the built-in
>#  set. The format of the files are described in hrtf.txt.
>#hrtf_tables =
>
>## 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 = 5
>
>## frequency:
>#  Sets the output frequency.
>frequency = 44100
>
>## resampler:
>#  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 = cubic
>
>## 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. 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
>
>## 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 behind the listener. This provides a
>#  "fuller" playback quality for surround sound 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 in
>#  front. This only has an effect when a suitable output format is used (ie.
>#  those that contain side and/or rear speakers).
>#stereodup = true
>
>## 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,core,oss,solaris,sndio,mmdevapi,dsound,winmm,port,opensl,null,wave
>drivers = oss
>
>## 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,
>#  dedicated
>excludefx = reverb
>
>## 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 =

>#  same speakers as the layout option are available, and the default settings
>#  are shown below.

>## default-reverb:
>#  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,
