That's the key thing, you need to have the audio managed out of ModemManager, either as a separate physical channel doing the audio right away, or via some other way, e.g. a ttyUSB port that you could use to route audio in userspace. In that latter case, we flag the ttyUSB as "Audio port" with udev tags, so that MM doesn't even try to probe it. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
