If the opening sequence is: stream1_open, stream1_hw_params, stream2_open, stream2_hw_params -> the constraints are set correctly for stream2. But if the sequence is: stream1_open, stream2_open, stream2_hw_params, stream1_hw_params -> than stream2 would receive constraint rate = 0, sample_bits = 0, since the stream1 has not yet called hw_params... The command to trigger this event: gst-launch-0.10 alsasrc device=hw:0 ! alsasink device=hw:0 sync=false This patch does some 'black magic' in order to always set the correct constraints and sets it only when it is needed for the other stream.
