I have a dell precision m6700.
When running Teamspeak as admin and then plugging in / unplugging a jack the audio drivers stops working completely. Only a complete re-install (uninstall-->install) fixes the problem. (Simply re-installing or re-adding device through device manager does not).
Might also occur with other programs (or when not run as admin), did not test this due to the hassle.
Env:
Win8.1, also occurred on Win8.
Driver version: Version 1.0.6491.0,A08 (12/11/2013, latest available)
Steps to reproduce:
1. Launch teamspeak as admin
2. Plugin or unplug sound jack (headphones/speakers)
3. Audio stops working completely. Only complete re-install of drivers solves.
