Hello Everybody
Currently I'm using Ubuntu 14.04 with a Spanish (Latinamerican) keyboard with multimedia keys for: volume up, volume down, mute, play/stop, previous song, next song, extract CD, and so ...
These special keys work perfectly after booting, nevertheless after the computer enters suspend mode, these keys stop working. None of them work after suspend. The only solution that I have found so far is to reboot my computer, but I would like to know if there is a way to avoid this, since it is quite anoying.

Thanks for your help
