+    <p>With the flat volume feature enabled, the sink HW volume is set
+    to the same level as the highest volume input stream. Any other streams
+    (with lower volumes) have the appropriate adjustment applied in SW to
+    bring them to the correct overall level. Sadly hardware mixer changes
+    cannot be timed accurately and thus this change of volumes can sometimes
+    cause the resulting output sound to be momentarily too loud or too soft.
+    So to ensure SW and HW volumes are applied concurrently without any
