I got a build error from this today, as the trace event tries to print the jack "name" field. I've managed to get it to build again by printing the "id" field in place of the "name". The name is normally assigned from id in snd_jack_dev_register using
snprintf(jack->name, sizeof(jack->name), "%s %s", card->shortname, jack->id);
but that code is not called here at all. My patch will slightly alter the output as a consequence, but I don't know if this change is critical or not.
