-        -- Volume control
-        awful.key({ altkey }, "Up",
-        function ()
-            awful.util.spawn("amixer sset " .. volume.channel .. " " .. volume.step .. "+")
-            volume.notify()

-        function ()
-            awful.util.spawn("amixer sset " .. volume.channel .. " " .. volume.step .. "-")
-            volume.notify()
-        end),
-        awful.key({ altkey }, "m",
-        function ()
-            awful.util.spawn("amixer set Master playback toggle")
-            volume.notify()
-        end),
