# WirePlumber, trimmed to what a microVM with no sound card actually needs.
|
|
#
|
|
# The goal is that `neswire` is the *only* Audio/Sink in the graph, so
|
|
# default-node selection has exactly one candidate and cannot pick wrong.
|
|
#
|
|
# The "Dummy Output" (`auto_null`) sink is not disabled here, because it does
|
|
# not come from this side. pipewire-pulse creates it with `module-always-sink`,
|
|
# and the pipewire-pulse drop-in turns that off with
|
|
# `pulse.cmd.always-sink = false`. WirePlumber ships scripts/fallback-sink.lua,
|
|
# which creates a node by the same name, but no component in wireplumber.conf
|
|
# references it, so it never loads. If auto_null appears, look at the
|
|
# pipewire-pulse drop-in first.
|
|
#
|
|
# pipewire.conf's Dummy-Driver / Freewheel-Driver are a third thing again:
|
|
# support.node.driver objects with no ports -- drivers, not sinks, so nothing
|
|
# can play into them. Dummy-Driver is load-bearing here. With no ALSA hardware
|
|
# it is what clocks the graph, and therefore what paces neswire's sink. Do not
|
|
# disable it.
