[kde-telephony-daemon] if sound is configured with 'internal speaker', after a missed call, it changes to 'internal earpiece'
Related GNOME Calls issue: https://gitlab.gnome.org/GNOME/calls/-/issues/452
How to reproduce:
- I move up and down the volume keys in pinephone, check that the "internal speaker" is selected
- Miss a call
- I move up and down the volume keys in pinephone again, and I see it is changing the "internal earpiece" volume (the expected is "internal speaker")
