9 to the audio jacks through debugfs interface, it is helpful to
10 validate ALSA userspace changes. For example, we change the audio
13 in this case, we could inject plugin or plugout events to an audio
14 jack or to some audio jacks, we don't need to physically access the
15 machine and plug/unplug physical devices to the audio jack.
17 In this design, an audio jack doesn't equal to a physical audio jack.
18 Sometimes a physical audio jack contains multi functions, and the
20 ``snd_jack`` represents a physical audio jack and the ``jack_kctl``
26 To inject events to audio jacks, we need to enable the jack injection
38 If users enable the SND_JACK_INJECTION_DEBUG in the kernel, the audio
