"codec not supported" seems to me an error coming from portaudio,

We just hand PortAudio a sequence of 16-bit samples, as far as I can tell; we're the ones who do the decoding (in decode_rtp_packet() in gtk/rtp_player.c).

However, *exporting* is a separate operation. It doesn't issue a "codec not supported" error. However, it *does* issue an "Unsupported codec!" error (note to the original poster - getting the text of an error message *exactly* right can be important, if we have to figure out where the message is coming from).
