13 The \fBaudio810\fR driver provides support for AC 97 audio controllers embedded
14 in Intel ICH, nVidia nForce, and AMD 8111 chips.

76 Some laptops (including Sony VAIO, among others), have their on-board amplifier
77 powered down by default, meaning that audio is suppressed even if hardware and
78 the \fBaudio810\fR driver are working normally. To correct this, set the
79 \fBac97-invert-amp=1\fR property in the \fB/kernel/drv/audio810.conf\fR to
80 power-up the amplifier.
84 In addition to being logged, the following messages may appear on the system
89 \fB\fBplay-interrupts too low\fR\fR
93 \fB\fBrecord-interrupts too low\fR\fR
96 The interrupt rate in \fBaudio810.conf\fR is set too low. It has been reset to
97 the rate specified in the message. Update \fBaudio810.conf\fR to a higher
104 \fB\fBplay-interrupts too high\fR\fR
108 \fB\fBrecord-interrupts too high\fR\fR
111 The interrupt rate set in\fBaudio810.conf\fR is set too high. It has been
112 reset to the rate specified in the message. Update \fBaudio810.conf\fR to a
113 lower interrupt rate.
