DAPM route objects such as:
Object.Base.route."1" {
source "dai.SSP.0.dai.capture"
sink "buffer.2.1"
}
will be converted to:
SectionGraph."Endpoint.route.1" {
index 0
lines [
"dai.SSP.0.capture, , buffer.2.1"
]
}
If the source/sink names are references to objects within a parent pipeline
object, the index attribute value can be skipped and it will be
populated when the object is pre-processed
Object.Pipeline.volume-capture."1" {
Object.Base.route."1" {
source "pga..0"
sink "buffer..0"
}
}
The reference pga..0 will need to be resolved to
get the widget name pga.1.0 and buffer..0 will
be resolved to buffer.1.0 before creating the SectionGraph as follows:
SectionGraph."volume-capture.1.route.1" {
index 2
lines [
"pga.1.0, , buffer.1.0"
]
}
