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.
