Description

Following issues can be observed when using CallAudioControl API on 3.1 device:

1. Muting and unmuting uplink doesn't work - returns error
2. Notification about uplink mute state doesn't work
3. Notification about output routing change doesn't work
4. Calling SetOutput(ELoudspeaker) breaks operation of CPeriodic objects with Idle priority
5. Calling SetOutput(ELoudspeaker) breaks operation of some CActive based objects (e.g. CLogViewRecent)

How to reproduce

1. Call CCallAudioControl::SetOutput(ELoudspeaker) and then create and start CPeriodic timer with priority Idle. The call back function is never called.
2. Call CCallAudioControl::SetOutput(ELoudspeaker), then create CLogViewRecent object and call SetRecentListL. The asynchronous call never completes.

Solution

3) Call CCallAudioControl::GetAvailableOutputs after a GSM call becomes active and the KOutputChanged is then reveiced properly.

4) Change Idle priority to any higher priority.
