When CallAudioOperation fails it invokes the set callback which usually points to `complete_command_cb()` to return the result to DBus. However cad_pulse_select_mode() invokes cad_pulse_mute_mic() without a callback set hence we crash in the error path like: #1 0x0000aaaad7949aac in cad_pulse_mute_mic (mute=0, cad_op=0xaaab15802f40) at ../src/cad-pulse.c:1097 #2 0x0000aaaad7949c5c in cad_pulse_select_mode (mode=CALL_AUDIO_MODE_DEFAULT, cad_op=0xaaab15809730) at ../src/cad-pulse.c:950 #3 0x0000aaaad7947b3c in cad_manager_handle_select_mode (object=0xaaab157e98d0, invocation=0xffffa4009c40, mode=0) at ../src/cad-manager.c:90 ... Guard against that case. Do so in other call sites as well so we don't hit the same problem should we invoke those functions internally as well. To reproduce run `callaudiocli -m 0` on a system that does't detect a suitable card.

When in calls, the audio isn't redirected over bluetooth headsets/headphones. This happens probably because we check for the droid sink and if it exists the earpice, speak and wired headset is enforced. This stops callaudiod from looking through other sinks to find an available port.
