AUDIO810 4D "September 12, 2020"
NAME
audio810 - Intel ICH series, nVidia nForce series and AMD 8111 audio core
support
DESCRIPTION
The audio810 driver provides support for AC 97 audio controllers embedded
in Intel ICH, nVidia nForce, and AMD 8111 chips.
FILES
/kernel/drv/audio810
32-bit kernel driver module
64-bit x86 kernel driver module
audio810 driver configuration file
ATTRIBUTES
See attributes(7) for a descriptions of the following attributes:
| ATTRIBUTE TYPE ATTRIBUTE VALUE |
| Architecture PC-based systems |
| Interface Stability Uncommitted |

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