Buffer error message.

Can anyone explain the error message when trying to run a program?

Cannot propagate frame-based signal from output port 1 of 'audioimport/Buffer' to input port 1 of 'audioimport/Mux' because this input port expects a sample-based signal. Consider inserting an Unbuffer in the signal path

I wish I can upload the diagram to explain clearly.

Thank You

The Buffer block from the DSP System Toolbox (Signal Processing Blockset prior to R2011a) converts a (regular) sample-based signal to a frame-based signal. The Mux block only works with sample-based signals, so it errors out when you feed in a frame signal.
