catch alsa exception on decibel acquire
This closes #17. For some reasons the alsa interface does not provide a dB value on all systems. Instead an error is returned. The alsa-mixer library checks for such return values and throws an exception if one is detected. This patch catches the exception and returns 0 as dB value.
