CAC release 1.0 (S60 3.1)

  • N95: muting and unmuting panics with USER 11
  • N95, E90: current uplink mute status gives error -1
  • N95: KOutputChanged notification works only after calling the GetAvailableOutputs while there is active GSM call
  • N95: Calling SetOutput breaks operation of all EPriorityIdle based active objects
  • N95: Calling SetOutput breaks Call Log reading. Following call to CLogViewRecent::SetRecentListL never completes, regardless the priority.

  • 6210: UplinkGainEvent() observer is called straight after calling AppendUplinkGainObserver() and the observer is not called after muting or un-muting as it should.
