driver provides support for S3 SonicVibes
(S3-617) chipset-based cards. Disabling the SRS 3-D spatial feature of the
chip is recommended for higher quality audio. This can be done in software by
issuing the following command:
$ mixerctl outputs.spatial=off
This driver is based on the
Lennart Augustsson. The sv
device driver first
appeared in OpenBSD 2.6
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 specified.
