+Subject: [PATCH] plugin: ogg: fix chucksize issue
+
+There are some OGG files that have metadata chucks that go over the
+hardcoded 10 * 4096 size due to album art. This patchset just parses
+each chuck and continues till it runs out of valid chunks.

+Subject: [PATCH 5/6] sink-input, volume: Add support for volume ramp factor
+
+Previously, using pa_sink_input_set_volume_ramp() is hard to manage
+if there are several callers. These new volume ramp factor APIs make it
+easy for caller to use and to set more than one volume ramp factor.
+New volume ramp factor will be applied by the multiplication of the other
+ramp factors that have been already set.
+
+APIs are added as below.
+ - pa_sink_input_add_volume_ramp_factor()
+ - pa_sink_input_remove_volume_ramp_factor()
+ - pa_cvolume_ramp_compatible()
+ - pa_sw_cvolume_ramp_multiply()
+ - pa_cvolume_ramp_valid()
