alsa-project/alsa-ucm-conf issue #777 was opened from qaqland:
On Acer S40-54, there is no "Input Source" enum control, so `If.micsetup` falls through to the `True` branch. However, the actual jack detection control is `Headset Mic Jack` not `Mic Jack`. As a result, the microphone is registered with no valid JackControl.
I applied this [change](https://github.com/deepin-community/alsa-ucm-conf/pull/9) on deepin and it works correctly on this Acer S40-54. But I'm not sure if this change is correct, and don't have other HDA devices to verify.
To avoid interference from the distribution, I confirm the above issue with the Fedora live system and generated alsa-info.
