alsa-project/alsa-ucm-conf issue #99 was opened from hzhuang1:
In v1.2.2, the content of HDA-Intel.conf is in below. v1.2.2 is widely used, such as in ubuntu 20.04.
```
Syntax 3
Define.Use "" # a non-empty string to use UCM configuration for HDA devices
Define.AcpCardId "$${CardIdByName:acp}"
```
With this content, pulseaudio can't load configuration from UCM. Then I tried to edit the content. Change it to
```
Define.Use "2"
```
or
```
Define.Use "3"
```
Pulseaudio worked with "options snd-hda-intel probe_mask=1" on DELL laptop.
My question is what's the real meaning of **Define.Use** at here. Why the default value of **Define.Use** is empty string? Even in v1.2.4, the **Define.Use** is also an empty string.
