[NAME] - Maxx Audio usually puts a blue W icon on the toolbar in the Notification area. Double-click that to open the Maxx control panel. Click Playback, which is the first big box on the left end of the top row. When that opens, there's a slider directly below the big speaker icon on left side. You can use that slider to turn Maxx off or on, and see if that helps your text-to-speech issue. Or, with that slider set to on, click the EQ Profile list just to the right of the slider and select Speech from the drop down list. See if that is better than turning Maxx off completely. Once you select an EQ profile, it keeps that same setting until you change it, like to the Movies option... Let us know if this helps.  
New XPS 8940 owner here, and I'm trying to conect my Logitech 5.1 surround system through the three analogue audio jacks. But Max Audio Pro isn't prompting me to choose the source anymore after I tried a couple times and had to redo a couple things and now only registers one connector as a headphone source. The front of te PC headphone jack also no longer works and when it did initially yesterday, Max Audio Pro tried to apply its simulated 3d audio which I can't disable as I use a screen reader, and the application isn't accessible with them. Wondering if anyone has any solutions? I've searched through the rest of the comunity but this is proving to be a challeng and , as someone who is totally blind and relies on speech and audio drivers to wrk correctly, don't want to risk trying any of the more fiddly solutions in case I break anything. Simply want to disable the 3d audio, get my 5.1 surround working, and have my headphone jack available when I want it. Any help appreciated. Thanks!
