The realtek audio driver seems to have an issue. Whenever I plug in a headset, this app called 'Max Audio Pro' pops up asking me what kind of headset I am plugging in. The audio works, however if I unplug the headset, there is no audio from the internal speakers. It should automatically change audio to internal speakers but it doesn't do that. I have to restart in order to get the sound back from internal speakers. The 'Max Audio Pro' app also has option to change audio to internal speakers but it doesn't work. I read somewhere online that says this app is like the bridge that connects your headset to the audio. Why do we have to go through an app to use our headset...? I've tried everything from uninstalling / reinstalling drivers and updating drivers. Anyone have any idea at all I would greatly appreciate it. I also got BSOD at one point when trying to switch to internal speakers in the 'Max Audio Pro' app. Obviously this is software issue, hope Dell fixes.
