Hi Martin, Due to the number of moving parts, I've opted to forgo using pulseaudio or pipewire on my system. Depending on how hands-on you are, you may like to try stopping those audio servers and attempt your experiments in a bare ALSA environment. Speech on linux predates pulseaudio and pipewire. In fact these sound servers mimic the underlying ALSA devices. So you can run speech without pipewire if need be, for debugging or as a system configuration choice. The main use case for pulseaudio was providing a centralized bank of volume controls for all applications playing audio. Pipewire adds handling the JACK audio connection protocol use for music production, replacing the function of the JACK audio daemon. In this case too, you can run JACK, and live quite comfortably without the extra features of pipewire.
