   1.106 +Patchable constant for licencee to set devsound server thread priority
   1.107 +Licencees should ensure that the devsound server thread priority is equal to the system server priority for better responsiveness.
   1.108 +If SYMBIAN_CURB_SYSTEMSERVER_PRIORITIES is defined, setting devsound server thread priority to EPriorityAbsoluteHigh will ensure
   1.109 +devsound server's thread priority is set to system server's priority.
   1.110 +If the macro is unavailable it is recommended to use EPriorityAbsoluteRealTime1. Usage of EPriorityAbsoluteRealTime1 requires ProtServ capability.
   1.111 +The constant can be changed at ROM build time using patchdata OBY keyword.
