* debian/patches/lp_992262.patch
- fix sound indicator not working after amarok close (LP: #992262)
* debian/patches/lp_902715.patch
- Partial fix which sets the accessibility property on the volume
slider menu item. Previously this was achieved by sending a signal
on the indicator object but now it seems the way to update orca is
to set/update the appropriate property on the menuitem. Orca doesn't
broadcast volume updates on slider movement but at least it updates
when the user moves to the item on the menu, previously it was entirely
silent. (LP: #902715)
