Title:
  Suspend in U/S 10.10 cancels Audio system operation.

Status in Ubuntu Studio:
  Won't Fix

Bug description:
  
  I have found that upon a timed system Suspend (as set in Power Management), the working 
  of the U/S sound system is interrupted and altered in its operation, or frozen, by the time 
  I reactivate the computer from Suspend mode. 

  Everytime Suspend occurs I have to restart the machine after Suspend to get anything to work,
  with regard Audio processing.

  *   *

  The critical Debug question concerning this issue is :

  How does a ReaL-Time system like U/S allow a destructive Suspend to 
  happen, when a critical process (Audio Processing) is under way, 
  without accurately saving everything that's required to achieve a 
  stable Restart, before Suspend is allowed to occur??

  SUGGESTION

  The current, in progress rewrite of Ubuntu Studio Controls could perhaps include a 
  setup system for Suspend mode. The resulting core set of variables could be the 
  basis for a system wide, access of Global system-control variables - this improvement 
  may pave the way for coherency across the modules - and therefore far better system 
  coherency and stability. 

  This setup could provide for a seamless Suspend mode and recovery from Suspend, to the exact 
  prior setup before the Suspend occurred. 

  Thanks
  Ken Gibbs
