M600i MdaAudio - ungracefully stopping playback

Hi all,
I'm porting an application from Pre-9.1 (Nokia 6680 in specific) to UIQ 3.0, 
and I've found that after calling CMdaAudioOutputStream::Stop, any 
subsequent WriteL call shortly reports MaoscBufferCopied(KErrAbort). The 
result is that the first audio stream I play is heard, but any following 
audio is not.
This is not very critical, since I do get MaoscPlayComplete(KErrUnderflow) 
once all audio has been played - unlike pre-9.1 Nokia devices where I had to 
set a timer and Stop audio output manually (the MaoscPlayComplete callback 
is needed for the application to behave properly - it must know that audio 
isn't playing anymore).
However, there are situations where I would like to stop audio as fast as 
possible, but also to be able to play more audio later... Anyone knows how 
to handle this problem?

TIA
Uriah
