I have installed Debian 10 on a laptop and on a desktop. I am trying to use a Wantek USB headset (earphones + microphone). On both computers I observe the same bizarre failures:
- The earphones play the Skype ringtones, but no other sound from Skype or internet.
- The microphone passes the online microphone test https://www.onlinemictest.com/ , but not the Skype call test.
Checking parameters on Alsamixer, and installing firmware-linux-nonfree do not help. Both computers work well if I plug a non-USB headset with two coaxial connectors (one for microphone, one for earphones). The headset works well with Ubuntu 18.04 on another laptop.
Any ideas on explaining these symptoms, and curing the disease?

Re: Bizarre failure of USB headset
Run this command in both distributions:
Then plug in the headset and compare & contrast the outputs in both to see what Ubuntu is doing differently.

Re: Bizarre failure of USB headset
Thank you for the suggestion. The main difference seems to be that Debian loads the two modules 'snd_seq_device' and 'snd_rawmidi', in addition to the two modules 'snd_usbmidi_lib' and 'snd_usb_audio' that Ubuntu also loads. See below for the raw outputs.

Re: Bizarre failure of USB headset
The desktop environment for the Debian laptop is KDE.
Thank you for your help and for the useful commands.
