I remember seeing a video of a demo of pulseaudio showing the connection and disconnection of an audio device and how a "send-to-all" virtual sink worked properly. However, the demo was with a GUI so I don't remember what commands could be given to pacmd to achieve the same effect. Good to know that you were able to solve the problem using mpd/udev. _r -------------- next part -------------- An HTML attachment was scrubbed...
