audio mode load change from Tourmaline Our FreeCalypso universe now has two kinds of audio mode config files: the old 164 byte kind and the new 176 byte kind. We are not enabling L1_NEW_AEC in Magnetite, only in Tourmaline, thus 164 byte audio mode files are still native to Magnetite. But we still desire graceful handling of the situation when a running Magnetite fw may load a 176 byte audio mode file (presumably with new AEC config), thus we incorporate the same audio mode loading change which we implemented in Tourmaline: if the loaded audio mode file is of the wrong kind, the AEC config is cleared to default disabled state.
