rlm@0 1 # OpenAL config file. Options that are not under a block or are under the
rlm@0 2 # [general] block are for general, non-backend-specific options. Blocks may
rlm@0 3 # appear multiple times, and duplicated options will take the last value
rlm@0 4 # specified.
rlm@0 5 # The system-wide settings can be put in /etc/openal/alsoft.conf and user-
rlm@0 6 # specific override settings in ~/.alsoftrc.
rlm@0 7 # For Windows, these settings should go into %AppData%\alsoft.ini
rlm@0 8 # The environment variable ALSOFT_CONF can be used to specify another config
rlm@0 9 # override
rlm@0 10
rlm@0 11 # Option and block names are case-insenstive. The supplied values are only
rlm@0 12 # hints and may not be honored (though generally it'll try to get as close as
rlm@0 13 # possible). Note: options that are left unset may default to app- or system-
rlm@0 14 # specified values. These are the current available settings:

rlm@0 99 # volume to compensate for the extra output speakers. True, yes, on, and non-0
rlm@0 100 # values will duplicate stereo sources. 0 and anything else will cause stereo
rlm@0 101 # sounds to only play in front. This only has an effect when a suitable output
