This results in having sound on speakers and on headphones at the same time. imho, the expected behaviour is to have sound only on headphones (without having to play with the mixer). This can be achieve with the presence detect capability (0x709,0xf09): When plug/unplugging the headphones, one gets an unsollicited responsed and the driver mute the channels. Is there something to do that in the code or should I go and code it ? Any opinion/comments about that ?
