Thank you very much for this hint. Indeed this changed a lot in
the right direction. It seems to me that the missing COM
initialization calls inside my worker thread were responsible
for the unexpected malfunction. Good to know that a global
COM initialization is not suffucient.

Unfortunately the output data is still not correct.
Actually the output file contains the complete sound data but
the result is twice as long and the sound plays back correctly
only for 5-7 seconds.
After that period of time the pitch decreases slowly (in about 2 seconds)
about 50% and stays on that level until the end of the sound.

Any clue what might be responsible for that?

1. I create an Audio profile 96KBit 44.1 KHz Stereo.
2. I create a Writer with WMCreateWriter()
3. I set the profile with pWriter->SetProfile()
