I assume it's a hand-rolled jackd. If so, I remember a Debian bug report
claiming the same alignment issue on ppc32 as seen on ARM:

     http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=728710

No guarantees, but maybe the following patch helps (also attached to
prevent corruption when displayed in web interfaces).


Please report back any findings.
