    hi sbdavid, did you want use pcm data.

    because all s60 phone support pcm formst.
    so, your code is very simply.
    you can find this link,
    it is about CMdaAudioOutputStream.

    for pcm, on MaoscOpenComplete, add
    Code:
    iPlayerStream->SetDataTypeL(KMMFFourCCCodePCMU8);
    or PCMU16 etc.

    for CMdaAudioInputStream,
    default data format is PCM,
    if you want use other format,
    add
    Code:
    iInputStream->SetDataTypeL(KMMFFourCCCodeAMR);
    etc
