It seems odd to me that your suggestion is to kill the package which *does* change the volume on Edward's headphones, which would leave him literally unable to change the volume at all. In my ignorance, that seems pretty counter-intuitive and unhelpful. Can you educate me please?
PulseAudio is an additional layer on top of the *actual* Linux audio system (ALSA). While it's no longer as buggy as it was when first introduced, more software layers = more difficult to figure out what's actually wrong.
It is possible that the cause of Edward's problem is Pulse grabbing onto something that it shouldn't. It's also possible I'm barking up the wrong tree entirely; what I saw of Pulse in its early days makes me inclined to distrust it, perhaps unfairly.
Which happend on my devuan (and former debian) systems any time. Kmix just does not work work with pulseaudio (on my systems). What's worse: alsamixer may work or not, depending on air pressure. So my suggestion is: If kmix should change volume, remove anything pulsaudio, then reboot, doublecheck if PA is really gone. Check if the firmware for soundblaster is loaded:
# dmesg |grep firm [ 5.889395] snd_hda_intel 0000:04:00.0: firmware: direct-loading firmware ctefx-desktop.bin
.. and the try alsamixer to change volume.
(And now someone else who has a Logitech headset is going to point to the exact problem, which will have nothing to do with any of this, and I'm going to look like an idiot. That's okay—it won't be the first time.)
If the headset is battery powerd it might have auto-gain, but I have never seen that in real live (most likely 'cause I run from battery powerd audio stuff). If the headset has a mic, it might also have auto-gain which is powered by the mic ghost voltage. Anyway, you should be able to figure that out .. my bet is, there's no auto-gain but PA doing "interesting" things.
