# PCM Class definition. All attributes defined herein are namespaced
# by alsatplg to "Object.PCM.pcm.N.attribute_name".
#
# Usage: PCM object can be instantiated as:
#
# Object.PCM.pcm."N" {
# id 2
# pcm_name "Headset"
# direction "playback"
# }
#
# where N is the unique instance number for the PCM object within the same alsaconf node.

# PCM name
DefineAttribute."name" {}
# PCM id
