[Fso] alsa player kills vibrator plugin

[Benjamin Deering]

Hello all,

A while ago I changed libphoneui to use FSO to control vibration when 
getting a call in SHR.  There was a problem where playing the ringtone 
would prevent the vibrator on gta04 from working again until fsodeviced 
was restarted.  Today I built player_gstreamer and it does not have the 
problem.  It seems to be specific to player_alsa.  Does anyone have 
ideas for where to look to fix this?  Calling aplay directly does not 
cause the problem.

Thanks,
Ben
