ok, now I get it. I didn't see the PA_ENCODING_PCM on the first line...

Still, I am not clear about the negociation. the client would need to
use pa_stream_new_extended with multiple formats, and then get the
actual format with get_format_info. If my understanding is correct,
then maybe you would need a list of formats instead of just one?

Yes, we can do this later.
