( https://gerrit.osmocom.org/c/osmocom-bb/+/17593 ) Change subject: mobile: add audio config, with unused audio loopback setting ...................................................................... mobile: add audio config, with unused audio loopback setting The aim is to add configurable audio loopback to mobile. An existing patch on a branch from fixeria [1] adds the audio config section. Add a reduced version of this audio config to be compatible with the future merge. Add the audio loopback setting, so far without functionality. Subsequent patch adds the actual loopback.
