Hi, I'm using an external dock which contains sound-output. One such dock-box at work, one in the home-office. Basically it's usb-connected with an additional external sound-device in the dock. Pulseaudio knows when the dock is not connected and falls back to internal sound-output. But is there a way to differentiate which of the two docks is connected, maybe by taking the serial-number of the dock into account? I didn't find any status of "speakers (not) connected" in pulseaudio for that device unfortunately. Of course that would work for me as well. My current idea was that at work where there are no external speakers connected currently it might want to use the internal sound while at home it should use the additional output from the dock. Kind regards, Stefan
