regressions in release 21022021

i noticed several regressions or small ui-bugs in release 21022021

• make sure floor attenuation combined with speakdetection works as intended: "floorVolume: 0.1" seems to have no effect (maybe our test-setup was flawed, and you can confirm "works for me")
• as interpreter the translator mic is muted on every switch when switching target language, please start muted and after unmuting once, never mute on language switch during the session (regression from #32 (closed))
  • fix by !22 (merged)
