In audacity, the Playback Device options I see (with no webcam or headphones plugged in) are several entries of the form "HDA NVidia: HDMI X (hdw:y,z)", for various values of X (0-5), y, and z; "pulse"; and "default". For Recording Device, I see "HDA Intel PCH: ALC3220 Analog (hw:0,0)"; "sysdefault"; "pulse"; and "default". > > > > > The Audacity tutorial says > > (https://ttmanual.audacityteam.org/o/man/tutorial_selecting_your_input.html) > > that "An audio host is an interface between Audacity and the sound card > > driver. ...

So HOST is not where you'd make any changes. > > > Thats interesting, if ALSA is the only option then where does PulseAudio > come in ? > My understanding is that pulseaudio is a sound server, which interacts with the applications and with the things that directly talk to the hardware. (See the comment in the text from the audacity tutorial above; it's not pulse that is the direct interface to the soundcard driver.) It seems that you have pulseaudio installed. Is it actually running? What does pavucontrol show? As I said, I haven't used audacity in a long time and on my system pulseaudio seems to be running and working just fine. But your configuration is clearly very different from mine and I don't know enough to help debug your configuration.
