So sorry for the misunderstanding.

I checked kdemultimedia3.spec and found;

  ./configure \
  $configkde \
  --enable-audio=$AUDIO \
  [...]

and,

  AUDIO="oss,alsa"

From my understanding, these mean that pipewire-alsa is required.

Anyway, I installed the package group that allows me to use
kdemultimedia3-mixer-3.5.10.1 from the above site.
Indeed,

	$ ldd kmix | grep asound
libasound.so.2 => /lib64/libasound.so.2 (0x00007ff0130bd000)
	$ ldd kmixctrl | grep asound
libasound.so.2 => /lib64/libasound.so.2 (0x00007ff0130bd000)

However, when I start kmix, the panel correctly displays my USBDAC as
a device, but it is unusable. So, when I execute

  $ kmix

then the following error is displayed, and when I check it, this error
is coming from kmixctrl.

$ kmixctrl

This makes me think that kmix does not assume the use of USBDAC, but I
don't know anything more than that.

Best Regards.
