sv 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
audio(4), intro(4), pci(4)
This driver is based on the
eap(4) driver by
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.
