You might try the commands manually (on lxterminal)...

To increase volume:* amixer -q sset Master 3%+ unmute*
To decrease: *amixer -q sset Master 3%- unmute*

It seems you have two audio cards, you may need to specify it on the

Try also: *amixer -c 1 -q sset Master 3%+ unmute*
*amixer -c 1 -q sset Master 3%- unmute*

If nothing of this works, check out* alsamixer*, what cards you have...
Press F6 to see if you have only one (0) or two (0 and 1) cards...
