Since I updated my realtek high definition audio driver through windows update ive been getting the following situation.I do be watching a video on vlc when a message comes up "you just unplugged a device from the audio jack" which I hadn't. At this stage I have no sound coming out my speakers but the sound is still playing according to my pc. I have reinstalled the driver numerous times. At the moment I'm using the windows default high definition audio device which is working for the last hour without stopping.. has anyone got any ideas rather than just reinstall the driver.
