All my null sinks disappeared.

[Esper89]

Every time I turn lyrebird on, all my null sinks disappear and my loopback devices that were using those null sinks get set to use the wrong sinks.

The null sink disappearing is intended behavior, since Lyrebird unloads all null sinks to prevent redirecting output to the wrong one. Cannot comment on the loop back device thing, but as of now there is no fix to this being implemented.
