Wys (https://source.puri.sm/Librem5/wys) manages the routing between the modem and codec by listening to ModemManager's state and connecting audio source and sink (again solely via pulsaudio so again just relying on modem and codec being alsa devices). Since the modem is not part of the SoC on the Librem 5 it's a completely separate device. Cheers, -- Guido > > Best regards, > > Pavel > -- > http://www.livejournal.com/~pavelmachek
