I use it regularly for videoconferences using various web-based meeting/conference apps. whenever I plug in the USB headset I have to use pavucontrol to manage sound. whenever it is not plugged in, I use the sound app in the upper menu, which turns out to be mate-volume-control (yes, I use the Mate desktop, not Gnome). This seems weird, but I've grown used to it. With skype, the audio settings menu refuses to admit to there being any such audio device attached to the system. Subsequent to my posting, I discovered that my ancient analog phone/mic headset works with skype, so I'm more or less set--except I like the Plantronics a lot better. it (the analog one, not the USB) has two 1/8 inch phone plugs, one pink, one green. plug 'em into the pink and green jacks, hack at the sound settings for a while, turn off the speakers (cause the system won't mute them when the phones are plugged in) and voila.
