Turn the volume way up in Windows and use the function keys to make sure the speakers are turned on and functioning before booting into Debian.
After booting on Windows, I could hear the sound from the speakers, so they were actually turned on. After that, I did a normal reboot, and booted to Debian...and no sound on speakers. The most surprising is that even speaker-test gives a sound through the headphone. best regards, -- Pierre Frenkiel
