# Volume playback pipeline
|
|
#
|
|
# A simple pipeline. All attributes defined herein are namespaced by alsatplg to
|
|
# "Object.Pipeline.volume-playback.N.attribute_name"
|
|
#
|
|
# Usage: this component can be used by declaring in the top-level topology conf file as follows:
|
|
#
|
|
# Object.Pipeline.volume-playback."N" {
|
|
# format "s16le"
|
|
# period 1000
|
|
# time_domain "timer"
|
|
# channels 2
|
|
# rate 48000
|
|
# }
|
|
#
|
|
# where N is the unique pipeline_id for this pipeline object within the same alsaconf node.
|
|
#
|
|
#
|
|
# (source) host.N.playback -> buffer.N.1 -> volume.N.1 -> buffer.N.2 (sink endpoint)
