62 # systems with apps that try to play more sounds than the CPU can handle.
66 # Sets whether to duplicate stereo sounds on the rear and side speakers for 4+
67 # channel output. This can make stereo sources substantially louder than mono
68 # or even 4+ channel sources, but provides a "fuller" playback quality. True,

149 # Sets whether to try using mmap mode (helps reduce latencies and CPU
150 # consumption). If mmap isn't available, it will automatically fall back to
151 # non-mmap mode. True, yes, on, and non-0 values will attempt to use mmap. 0
152 # and anything else will force mmap off.
161 # Sets the device name for OSS output.

173 ## Solaris backend stuff
178 # Sets the device name for Solaris output.
181 ## DirectSound backend stuff
185 # Sets the number of updates for the output buffer.
189 ## Windows Multimedia backend stuff
194 ## PortAudio backend stuff
199 # Sets the device index for output. Negative values will use the default as
200 # given by PortAudio itself.
204 # Sets the number of update buffers.
208 ## PulseAudio backend stuff
213 ## Wave File Writer stuff
218 # Sets the filename of the wave file to write to. An empty name prevents the
219 # backend from opening, even when explicitly requested.
