my Thinkpad X230 is sitting on a Lenovo docking station (Minidock Plus) and I have a USB audio interface (NI Komplete Audio 6) connected to the dock. It works fine when I boot the computer while it is sitting on the docking station.
If I dock the Thinkpad (while running or while suspended) Ubuntu 12.10 does not re-connect the USB audio interface. Instead it continues to play back audio via the internal sound hardware. The Komplete Audio 6 is shown in the sound settings but choosing it changes nothing (the sound is still being played back via the internal hardware).
I have to re-boot on the dock to get the USB audio running again.
Any ideas for correcting this behavior?
