      alsa-project/alsa-ucm-conf issue #442 was opened from thenameisluk:
i have similar config to https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/Qualcomm/sc71...
for [homestar](https://wiki.postmarketos.org/wiki/Lenovo_IdeaPad_Duet_5_(google-homestar))
```
# Use case configuration for ALC5682+MAX98357A on SC7180
SectionVerb {

    	TQ "HiFi"
    }

```
the speaker and mic section is irrelevant here
hdmi is causing issues
without
```
    ConflictingDevice [
    	"Speaker"
    ]
```
pipewire doesn't want to use the ucm at all unless the hdmi is plugged in
with it
pipewire will only configure hdmi if hdmi is plugged in (when you restart it or at boot)
it's all on the same card
and the interface never goes away, only switches between
```
# amixer -c 0 contents
numid=9,iface=CARD,name='HDMI Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
...
```
without hdmi and
```
# amixer -c 0 contents
numid=9,iface=CARD,name='HDMI Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=on
```
with hdmi
```sudo alsactl monitor```also shows
```
node hw:0, #9 (0,0,0,HDMI Jack,0) VALUE
```
when plugging in and unplugging
knowing all this i am unable to figure out how to handle it with ucm2
and would appreciate some help getting it working without that ConflictingDevice
