But when I plug my old Nokia headset which has 4 pin jack (last pin is ground and it has both mic input and speakers output), kernel autodetect that something was inserted and automatically switch input from internal mic to jack mic. So somemthing now detected that headphones with microphone was inserted... So why cannot be that autodetection used also for switching audio output from internal laptop speakers to headset jack? Also I tried normal headphones (without mic, 3 pin jack) and nothing switched microphone input. So really HW/kernel/PA can somehow distinguish between headset and heaphones -- because I see in PA port config that input is automatically changed when I plug/unplug Nokia headset. Or I missed something?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
