I have with me a Dell Latitude E4300. But whenever the mouse pointer is over the speaker, it notifies that I run an update and have no audio output device installed now. I have also tried running the diagnostics and the output but I have failed to generate interrupt 1b63:0268. I was wondering if someone knows how to get sound back on my computer. I am really pissed off with the situation. Any advice and suggestion will be highly appreciated.
