Not sure what you mean by sync option.  What seems somewhat relevant in
the man page is:

 -L --async-latency
 Extra output latency in asynchronous mode (percent) (default: 100)

There is a process running like this:

/usr/bin/jackdbus auto

Should it also be terminated between each test along with jackd itself ?
