I suggested this maybe a month ago on a German FR-forum, I'm still waiting for results but I've been promised they'll eventually come in. :-) Don't forget you have to set up FR to actually not switch to headset.state when inserting a jack. Easiest way to me seems to rename/delete original gsmheadset.state file and replace it by a copy of gsmhandset.state We would appreciate very much every report on this, preferably of the result of inserting short-jack during a call with buzz. Also particularly I myself would "love" to hear reports of reproduceable bad buzz in Germany PLZ-90xxx (Nuernberg/Fuerth/Erlangen), so I would get to know about a place where I actually could travel to, to test buzz myself here :-) cheers jOERG
