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

61 record-interrupts too low set too low. It has been reset to the
62 rate specified in the message. Update
63 audio810.conf to a higher interrupt rate.
