Bug Description
After upgrading from Kubuntu 20.04 to 20.10, PipeWire gets installed and started along with PulseAudio. As a result, upon system startup some audio output and input devices are not visible in PulseAudio. For example, a Builtin audio device might not have analog output or duplex modes - only digital output. Another audio device might not have 5.1 analog output + analog stereo input mode, but have other modes (e.g. stereo duplex or digital output). This may not happen the same way every time - on some start ups some of the devices may be fully visible in PulseAudio, on others - not.
Presumably, PulseAudio cannot access these devices fully because PipeWire grabs these devices on startup.
The problem is solved if pipewire and dependent packages are purged from system.
