When a Windows 8 ThinkPad Yoga is connected to a ThinkPad OneLink Pro Dock (Model DU9033S1) which has a sound cable placed into its headphone jack, every few seconds the sound will alternate between the laptop speakers and the docking station. It appears that the connection to the docking station is briefly lost (sound comes from laptop speakers), and then re-established (sound goes to docking station). However, during this "disconnect/connect", all other aspects of the docking station are unaffected (video, network, USB).
Updating BIOS, audio drivers, dock drivers & firmware have had no impact. If sound cable is removed from dock, then behaves normally (sound goes to dock only). Happens with multiple Thinkpad Yogas and multiple docking stations.
Mod's Edit: System model added to front of Subject line to improve visibility / clarity.
