Steam can't see my ps4 controller. When I plug my PS4 controller in via usb the controller audio device will appear and disappear in the pavucontrol app and the alsamixer app. As well the current audio device will alternate between my usual device and the controller. I cannot use any pavucontrol settings because it disappears too fast, and seems to be reset each time it reappears. Alsamixer claims the sound device was unplugged. The blipping doesn't happen when I connect it only over bluetooth without the usb, but steam still can't see it. I have attempted to set the default-sink in the config files, but the files that get generated in .config/pulse are still blank.
I have modified the various config options in two ways to attempt to fix this. I've commented out any pulse audio modules related to bluetooth and usb audio devices (I only have the controller so no harm), and I have also commented out the "switch to newly plugged in devices" module. Neither change had any effect on the issue. I attempted to find every instance of the pulseaudio config files on my machine to ensure there is no hidden config file I forgot to change. I could not find the individual device profile files for pulse or alsa, because I'm not that experienced with linux audio systems.
I also have ds4drv installed and that has not had an effect on the audio behaviour either.
I briefly tested the controller on windows to make sure that it wasn't a controller hardware issue and it seems to connect just fine.
I had trouble following the pulse audio log instructions at https://wiki.ubuntu.com/PulseAudio/Log, if someone has a link with instructions specifically for 20.04 let me know.
