NOTES

50       Some laptops (including Sony VAIO, among others), have  their  on-board
51       amplifier  powered  down  by  default, meaning that audio is suppressed
52       even if hardware and the audio810 driver are working normally. To  cor‐
53       rect   this,   set   the   ac97-invert-amp=1   property  in  the  /ker‐
54       nel/drv/audio810.conf to power-up the amplifier.

DIAGNOSTICS

57       In addition to being logged, the following messages may appear  on  the
58       system console:
59
60       play-interrupts too low       The  interrupt  rate  in audio810.conf is
61       record-interrupts too low     set too low. It has  been  reset  to  the
62                                     rate  specified  in  the  message. Update
63                                     audio810.conf to a higher interrupt rate.
64
65
66       play-interrupts too high      The interrupt rate set inaudio810.conf is
67       record-interrupts too high    set  too               high.It  has  been
68                                     reset to the rate specified in  the  mes‐
69                                     sage.   Update  audio810.confto  a  lower
70                                     interrupt rate.
