MPEG-TS doesn't (usually) contain any more detailed information than the
codec used.  It's up to your mpeg audio decoder to detect a change, and do
something sensible.  It's probably not a very good idea to be changing audio
parameters midstream, as most players will not cope with it.  I'm not sure
whether it's (dis)allowed by any standards.
