Audacity not showing pulse audio option. I tried installing "alsa" but there is no such thing. I tried installing alsa plugins, but "make" does not work after configuration. I tried running pulse audio, but I get
E: [pulseaudio] main.c: pa_pid_file_create() failed.
It is a fresh ubuntu install
I was able to get it to work by following this tutorial in the official Audacity doc. Primarily:
pavucontrol
Sorry probably a bit late for you now but I have Audacity running on Ubuntu 20.04 with a Behringer UMC404HD using the following command line: pasuspender -- audacity both input and output works fine. Be aware there is a lot of low level clicking during the setup process but it does not seem to affect the results. It seems the other options offered by Ubuntu are not functional at this time.
