+Subject: [PATCH 2/2] acp: reset soft_volume
+
+Reset the software volume when initializing the device and when the
+hardware volume is updated.
+
+The software volume was set to 0 by default and if the session manager
+did not change the volume enough to cause a software volume change,
+it would remain 0 and there would be silence.
+
+Also improve the debug a little.
+
+See #1160 #1167 #1164 #1049 #1117
