# This can be dropped with PulseAudio 17
From b16b107171f24f791f79c20730cf6eb3ad469944 Mon Sep 17 00:00:00 2001
From: Arun Raghavan <arun@asymptotic.io>
Date: Tue, 20 Oct 2020 16:18:57 -0400
Subject: [PATCH 1/3] echo-cancel-test: Drop references to internal message
queue
We don't actually initialise or use it in the test, and this just causes
a crash at the end.
