37 .Nd "nvlist-based PCM audio device enumeration interface"
48 device allows callers to enumerate PCM audio devices available for use.
121 Whether the PCM audio device node is created by in-kernel audio subsystem or
126 The PCM audio device node relative path in devfs.
128 The description of the PCM audio device.
131 This can be 0 if this PCM audio device does not support playback at all.
134 This can be 0 if this PCM audio device does not support recording at all.
137 This exists only if this PCM audio device supports playback.
153 This exists only if this PCM audio device supports recording.
169 This field may not exist if the PCM audio device is not provided by in-kernel
256 A string specifying the provider of the PCm audio device.
262 Drop any previously fetched PCM audio devices list snapshots.
265 Generate and/or return PCM audio devices list snapshots to callers.
271 If there is no existing PCM audio device list snapshot available in the
274 a new PCM audio device list snapshot will be automatically generated.
293 Once a PCM audio device list snapshot is returned to user-space successfully,
298 Add a list of PCM audio devices provided by callers to
309 Userspace-backed PCM audio device nodes should be listed inside the serialized
