Bjorn RE: (If it was an incompatibility, sound would be restored after unloading the modem modules.) Excellent point. This infact has not been checked! Hefri, The first tests are to ascertain whether there is sound before manual loading of the modem drivers with: $ sudo modprobe agrmodem $ sudo modprobe agrserial If so, can sound be recovered aftrer a modem session by: $ sudo modprobe -r agrserial $ sudo modprobe -r agrmodem Others users of this driver set ,including the patched snd-hda-intel.ko, have not reported sound loss. So if the problem is not fixed as suggested, we should report it to the ALSA maintainer, as a problem to be addressed for the ALC268 Analog audio chip set case.
