I also do not get any sound at all during the ePSA pre-boot diagnostic. I have done everything I can on the software side of things, replacing drivers, reinstalling windows fresh and fresh installations of all the latest drivers, all configurations are properly setup for internal speakers, the internal speakers are detected and set as the default device, alienware sound center says "internal speakers" selected, when connecting headphones it says headphones, when unhooking headphones it properly transitions back to internal speakers. No sound from the internal speakers but headphones and external speakers via the 3.5mm jack work fine.
