PulseAudio (and JACK) are being replaced with Pipewire on modern systems and we may need to explicitly support this in order for audio to work in a ThinLinc session. It is unclear when this is needed though as Pipewire still recommend using the old APIs even if Pipewire is the backend: > We recommend that you continue to use PulseAudio, JACK and ALSA API's for now. https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ Fedora 34 is shipping with Pipewire instead of PulseAudio so that will likely be the first we see of how this behaves.
