Hi!
Your patch does not apply to current jackd upstream. The target has
moved from example-clients to tools, however, signals have been removed.
Find attached the reworked patch, but it doesn't work, at least not with
the dummy client (I currently have no other free cards ;).
I suggest to close this bug and you contact upstream (jackaudio.org)
directly.
Cheerio
