Soft jack injection for USB audio?
I have the need to use soft jack injection to debug userpsace, but currently USB audio doesn't have that ability.
The problem I am facing is that the USB audio doesn't use snd_jack_* to control the jack, so we can add the support for USB audio separately.
It's not hard to add the support if we open code soft injection in USB audio's build_connector_control(), but would it be possible to use snd_jack_* in USB audio?

I haven't checked that path yet, but I see no reason why it wouldn't work.
