Volume control does not always work in Mavericks
On my MacBook Pro, every now and then (almost every other time I start it) the volume control is not enabled. Anyone else having issues? Any solutions that don't require restarting? MacBook Pro bought in 2010, 2.53 GHz Intel Core 2 Duo, 4 GB RAM. OX X 10.9.
