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 cor‐
rect this, set the ac97-invert-amp=1 property in the /ker‐
nel/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 The interrupt rate in audio810.conf is
record-interrupts too low 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 The interrupt rate set inaudio810.conf is
record-interrupts too high set too high.It has been
reset to the rate specified in the mes‐
sage. Update audio810.confto a lower
interrupt rate.
