[AOD255E, Realtek ALC272X, Green Headphone Out, Left] No automute

[johnmic]

The sound continues to come from the internal speakers once I have plugged my headphones in - this problem does not occur when I use Windows 7 on the same computer. Furthermore, the sound quality in the headphones is poor, with a constant white noise.
