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 latest code, the **Define.Use** is also an empty string.
