modules: handle stream trigger errors

Browse source 
When we get a process callback from the capture stream but we can't
trigger the playback stream, simply consume the buffers from the capture
stream.

This can happen when the playback stream is not ready yet, for example.
If we don't consume the buffers that are ready, the converter might run
out of buffers and complain.
