+Subject: [PATCH] Port from GConf to GSettings
+
+Summary:
+CCBUG: 386665
+
+As discussed in bug 386665 GConf is deprecated and needs to be replaced by GSettings to keep features enabled.
+
+Question: Do we need GConf as a fallback for PA versions without module-gsettings?
+
+Test Plan:
+Checkboxes in Advanced tab are enabled again.
+Changed settings are shown in dconf-editor and vice versa.
+Combine output checkbox shows/hides combined sink in applet
