  1. Have improved my Inspiron 4150 Vista Ultimate and now the audio is not working. Tried updating the BIOS and still nothing. What is strange is that Device Manager shows no conflict and the little icon of a speaker-mute in the system tray. Do not know what the deal is no more than if someone has found a solution that could use it.
