AAC LC Audio Codecs Problems On DM648 Evaluation Board

Hello There:

I'm trying to work on the audio codecs provided by TI with the DM648 evaluation board. I'm using AAC LC codecs and I have the following problem:

When creating the codec, an error comes:

  self->hCodec = AUDENC_create(self->hCodecEngine, self->codecName, &self->audencParams);

Now if:

  self->hCodec = AUDENC_create(self->hCodecEngine, self->codecName, NULL);

then there is no error, however when setting dynamic parameters an error comes again:

status = AUDENC_control(self->hCodec, XDM_SETPARAMS, &self->audencDynamicParams, &self->audencStatus);

Any idea of what is happening and how to fix this problem?

Thanks;

Gabriel
