With SOF enabled in sof-hda-generic.tplg device (no DMIC) the control 'Capture Source' is not controlled by UCM

[GitHub issues - edited <github@alsa-project.org>]

alsa-project/alsa-ucm-conf issue #484 was edited from singalsu:

The configuration is not usual. If there is no DMIC in the system usually the legacy mode is selected (as with `options snd_intel_dspcfg dsp_driver=1`). In such PCs SOF can be enabled with `options snd_intel_dspcfg dsp_driver=3`.

When a headset is plugged/unplugged the playback correctly switches between speaker and headphone/headset earbuds.

But the microphone capture remains muted. I noticed with legacy mode where internal microphones work that control name='Capture Source' changes to 1 when headset is removed:

```
singalsu@asteri:~$ amixer -c0 cget name='Capture Source' 
numid=6,iface=MIXER,name='Capture Source'
  ; type=ENUMERATED,access=rw------,values=1,items=2
  ; Item #0 'Headset Mic'
  ; Item #1 'Internal Mic'
  : values=1
singalsu@asteri:~$ amixer -c0 cget name='Capture Source' 
numid=6,iface=MIXER,name='Capture Source'
  ; type=ENUMERATED,access=rw------,values=1,items=2
  ; Item #0 'Headset Mic'
  ; Item #1 'Internal Mic'
  : values=0
```

This is not happening when SOF is enabled. But I could make internal microphones capture work with `amixer -c0 cset name='Capture Source' 1`.  Is there a way to fix this in ucm2? I'm not absolutely sure about this issue in Fedora 41 but this happens with my ucm2 development code with plain git master branch (commit 0782bf435b8332833e7b3fc91501d78473dd6edf).
