28 Also, assuming it's KDE then also run pavucontrol-qt (or whatever it's
29 called on your system) to ensure you see the application generating
30 audio is actually doing what you think it is - there's an app-by-app
31 set of VU meters showing where KDE is sending audio in terms of
32 which hardware output.
33
34 I.e. - KDE can send audio from different apps to one or more
35 hardware devices at the same time. pavucontrol should allow
36 you to see how this is happening at any time. I have it in my
37 favorites.

39 Good luck,
