In my probe function, after adding the controls, I added the following code retval = snd_jack_new(intelmaddata->card, "Headphone", SND_JACK_HEADPHONE, &jack); if (retval < 0) return retval; jack->private_data = jack; snd_jack_report(jack, jack->type); retval = snd_jack_new(intelmaddata->card, "Headset", SND_JACK_HEADSET, &jack); if (retval < 0) return retval; jack->private_data = jack; snd_jack_report(jack, jack->type); But I do not see any jacks in /dev/input.... Am I missing anything?
