It "just works" in the default configuration on traditional hardware, where plugging the headphones in does not result in the need to move streams to a "different" sound card. I have slightly unusual hardware in the form of a Dell Inspiron 7415 laptop (with its internal microphone and the headset microphone presented as two separate SOF cards), and there are two trouble points: * The external microphone level is not saved/restored across the reboot, making the other party complain that my voice is clipping * The echo canceller configuration is static - once loaded, it does not react to the headset plug/unplug events and always uses the same microphone.
