HISTORY    [Toc]    [Back]

     This  driver  is  based  on the eap(4) driver by Lennart Augustsson.  The sv
     device driver appeared in OpenBSD 2.6.

BUGS    [Toc]    [Back]

     The "FM" DAC, wavetable synth, and MIDI port  are  not  supported.  Recording
  at  a  rate different from playback is supported by the
chip but not
     the driver.  The mixer does not  allow  control  of  reverb,
digital loopback,
  or 3-D SRS features.  The chip does not support exact
record speeds
     (it seems) of 11025hz, 22050hz, and so on, used  by  Windows
audio.  Usually,
  the  actual  record  is  rate is around +/- 50hz of the
