NOTES

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.

DIAGNOSTICS

In addition to being logged, the following messages may appear on the system console:

play-interrupts too low

record-interrupts too low

The interrupt rate in audio810.conf is set too low. It has been reset to the rate specified in the message. Update audio810.conf to a higher interrupt rate.

play-interrupts too high

record-interrupts too high

The interrupt rate set inaudio810.conf is set too high.It has been reset to the rate specified in the message. Update audio810.confto a lower interrupt rate.
