Some laptops (including Sony VAIO, among others), have their on-board amplifier powered down by default, meaning that audio is suppressed even if hardware and the audio810 driver are working normally. To correct this, set the ac97-invert-amp=1 property in the /kernel/drv/audio810.conf to power-up the amplifier.
