.SH 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 \fBaudio810\fR driver are working normally. To correct this, set the
\fBac97-amplifier=0\fR property in the \fB/kernel/drv/audio810.conf\fR to
power-up the amplifier.
