48 device allows callers to enumerate PCM audio devices available for use.
123 Whether the PCM audio device node is created by in-kernel audio subsystem or
128 The PCM audio device node relative path in devfs.
130 The description of the PCM audio device.
133 This can be 0 if this PCM audio device does not support playback at all.
136 This can be 0 if this PCM audio device does not support recording at all.
139 This exists only if this PCM audio device supports playback.
155 This exists only if this PCM audio device supports recording.
171 This field may not exist if the PCM audio device is not provided by in-kernel
262 A string specifying the provider of the PCm audio device.
268 Drop any previously fetched PCM audio devices list snapshots.
271 Generate and/or return PCM audio devices list snapshots to callers.
277 If there is no existing PCM audio device list snapshot available in the
280 a new PCM audio device list snapshot will be automatically generated.
299 Once a PCM audio device list snapshot is returned to user-space successfully,
304 Add a list of PCM audio devices provided by callers to
315 Userspace-backed PCM audio device nodes should be listed inside the serialized
