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:
This driver is based on the eap(4) driver by
Lennart Augustsson. The
$ mixerctl outputs.spatial=off
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.
