"All buffers in a queue must have the same format and attributes."  
That's pretty clear.  Buffer attributes include frequency, bits, 
channels, and size (although I think most implementations _are_ tolerant 
of varying sizes).

Feel free to try it out.  Some implementations might not care (software 
implementations in particular), but I wouldn't expect every 
implementation to work.  This is the kind of thing that hardware hates, 
for example.

What exactly are you trying to do in your application?  There might be a 
way around the problem.
