[pulseaudio-discuss] [PATCH 3/3] module-role-ducking: Add argument duck_while_corked

[Juho Hämäläinen]

With this enabled when trigger stream is available but
in corked state trigger is already applied to interaction
streams. This is useful when trigger stream pauses for
a while before playing, so that the trigger happens
slightly earlier.
