Subject: [PATCH 1/6] aplay: Fix invalid file size check for non-regular files

aplay tries to check the file size via fstat() at parsing the format

headers and avoids parsing when the size is shorter than the given

size.  This works fine for regular files, but when a special file like

pipe is passed, it fails, eventually leading to the fallback mode

wrongly.

A proper fix is to do this sanity check only for a regular file.
