perhaps you might want to try strace, redirecting output to a file,
like

  strace -f -o <tracefile> play foo

once as normal user, once as root and try to compare the outputs
(the -f option is there for strace to follow child processes on
fork).

It'll be a lot of output, but perhaps you can spot some relevant
differences.
